Yeah I have studied 3 languages to quite high levels and have two science degrees and I can tell you you’re taking an incorrect and simplistic view of both.
I don’t think it makes you incapable of having an opinion, I’d just expect some kind of knowledge of a subject when having such a strong opinion on it.
Why does it offend you so much? Surely being civil to what is a very small minority of society to vastly improve how they feel while having no real adverse affect on your life is a good thing.
