So like, just because you 'studied' linguistics you think that makes you an expert on how language should always be used or that people should not feel a certain way about language just because you say so?

That's not exactly a compelling argument.

Language is always going to carry certain meanings for some folks and we do a disservice to people by ignoring that, we all have our own personal lexicons/semantic meanings to a degree and that will likely never change, we do best by understanding this and working together to understand and accept when certain language can be hurtful and thus find ways of talking that do work for each other.

I feel that's a better way of being than talking down to someone like you just did and telling them that how they feel about it doesn't matter and they should just get with the program, which is never going to work.
