So, not to make any personal statements about you, specifically, Diana, but there’s two things you could consider.
First, on the term itself:
‘Xenophobia’, like many other sociology terms expressed as ‘-phobia’ isn’t actually about direct and immediate fear. It’s about bias. Specifically “dislike of or prejudice against people of other nations.”
While the specific term used in this case has a ‘-phobia’ partial root, equivalent terms are ‘ethnocentrism’, ‘jingoism’, ‘isolationism’, and ‘radical nationalism’. The ‘-phobia’ category seems to have caught on as a catch-all usage because it’s, well, catchy. It’s an easy thing to group things into those categories, even if ‘fear’ isn’t a direct part in the behaviors that express. A more common immediate behavior tends to be aggression—including but not limited to violence. Aggressive responses can be as mild as derision or an expectation of poor behavior, even if the individual hasn’t yet demonstrated any poor behavior.
Digging deeper, though, fear does play a strong role in fomenting those behaviors and biases. Usually, this isn’t a conscious fear. This isn’t something where the biased individual is aware of feeling afraid. Rather, it’s the same undercurrent that triggers the aggression in the first place.
Aggression, after all, is a fear response. All aggression, all anger, is rooted in fear.
Think of something that makes you angry. Anything at all. It will, invariably, be something you feel is ‘not right’. It can as simple as something being out of place, someone you don’t like being present or speaking, someone speaking out of turn. Anything that offends propriety or presents any conditions that are not desired can trigger anger. That’s not to say that it always does, but it can. And it’s useful to understand why, especially in terms of societal ‘-phobias’.
Things that aren’t as they should be, that aren’t as we desire them, are a challenge to our desired order and outcome. From the innocuous and ephemeral matters like ‘where did I leave my nail clippers?’ to ‘something wants to eat me’, and definitely including ‘that bastard is tracking dirt into my clean and orderly home’, they constitute a challenge to the patterns our brains expect.
Our brains are pretty much hard-wired to want patterns to match expectations. We work very hard to make sure our personal patterns conform to the expected patterns… or at least, appear to do so well enough for us to feel like they do. When things don’t match the expected and desired patterns… something is wrong. Either the outside world is not conforming to the behaviors it should, or our understanding of our patterns is wrong. The potential exists that our brain is not matching and predicting patterns properly. That there is something wrong with us.
None of that process occurs at the level of conscious thought. Anyone with any interest in the study of the human mind, by now, should be very well aware that the conscious mind is nothing but a construct, assembled as a means of interpreting aggregate data by the deeper functions of the brain1. But those deeper functions do react to the world around us, and influence the conscious mind in ways we don’t consciously recognize in the moment.
In the case of literally anything that indicates there might be something wrong with us, our pattern-matching-and-predicting brain recognizes that if it cannot accurately match and predict patterns, that impairs our chances of survival. We are, after all, talking about the parts of the brain that read everything in terms of primitive, animal response. The parts that are concerned, first, foremost, and only… with surviving. So those parts see any challenge to our ability to survive as a cause for fear.
In almost all cases, unless there is a real threat that the rest of our brain, either conscious or more primal, can verify, this fear gets allayed, minimized, or mitigated. But it’s the source of that gnawing dread that comes from minor incidents. It’s why when you lose something stupid, like nail clippers, you keep working the problem in the back of your mind, you get distracted and keep finding yourself glancing around thinking ‘I always put them right there… where the hell would they be?’ and so on.
We don’t consciously perceive it as fear, but that’s where its roots lie.
It also manifests as anger. It is, in fact, exactly that underlying fear that causes more or less all anger. Anything you’re mad at is a challenge to your expected normal patterns. Anger is your brain’s chemical release telling you to FIX IT!!! In essence, anger is your deeper brain activity deciding ‘The problem can’t be internal, it must be external. I will remove the problem and stop letting it make me afraid!’ It’s the ‘fight’ of ‘fight or flight’: Either remove the problem, or remove yourself from the problem’s proximity.
So, any time you feel aggression? Any time you feel like you need to duel someone, or demean them, insult them, belittle them? There’s an underlying fear there, of some sort.
In the case of xenophobia, the underlying fear is usually that the influence of ‘outsiders’ will make things not conform to the ‘proper’ order of daily life. They’ll say and do things that disrupt the expected patterns. They may even change those patterns over time, forcing you to adapt to their patterns. And that cannot be allowed… after all, if you’re adapting to their patterns, then your patterns… were wrong. You were wrong. You were not anticipating patterns correctly. You might die.
Again, all well below conscious levels.
Edit: Also, for @Branka_Adovic: This is me starting to warm to a topic, and composing a short-but-complete response. It is still not a true ‘text wall’. You’ll notice, you never got this far.
1. The classic ‘clapping at a distance’ experiment is an easy indicator of this. The moment where the sound and light of the person clapping reach your senses at a greater difference than your brain’s ‘blurr’ of reconstructing events, you’re suddenly aware of the separation, and it’s just… weird to experience.
