Yet every native speaker in this off-topic discussion understood his meaning fine. So no, not by any perspective. In this case, only by yours.
Sometimes it’s worth just acknowledging our own limitations and accepting that others actually do know what they are talking about, even if you can’t quite comprehend it, through no fault of your own.
Just to be clear : Just because you are ten people agreeing together does not make you right. You can be ten people wrong.
I told you why your definition can’t be used in that context. All you got was “no we all agree it’s correct”, which is not an argument about its correction, but an appeal to popularity, and you trying to dodge my point with fallacious arguments.
Obviously not, because if you had you wouldn’t be telling me that I can’t use the word defend in the context that I did; a context that was clearly understood by others.
I’ll accept that word defend has different meanings depending on how it’s used, the way in which I used it is apparently acceptable to speakers of English in at least 3 different countries where English is the most prevalent language.
