Reading. It’s what’s good for you.
I’m fine with the OP’s post, it’s perfectly normal to want to vent a bit when you get an overdose of snark in one day. As you say however, there’s more to communication than just the words typed. There’s tone, intent, and delivery, all of which don’t come through very well, or are easily misinterpreted, when all you’ve got is words on a screen.
The OP’s post could easily have been interpreted by someone not giving the benefit of the doubt as:
"EVE players are a bunch of snotty shut-in incels.
You geeks aren’t as hot as you think you are.
I’m upset, and whatever upsets me interferes with “growing the community”.
For the good of the game, I want the people who annoy me kicked out of chat.
You dickheads are making me very angry."
It’s not terribly surprising that 3/4 of the responses he got are negative, particularly considering that EVE is very much not positioned as the Mr. Nice Guy of MMO games. The forums have more than their share of malcontents looking for an argument.
At any rate, Rookie Help isn’t going to become a haven for the hapless to have their hurts tended any time soon. Anyone in EVE can pretty much expect a hefty dose of salt with their sugar, whatever the venue. People can either learn coping strategies and situation re-framing to deal with it, leave, or be miserable.
At least we still have freedom of choice.
