Bigots are not welcome on my post and they are certainly not welcome on my post to co-opt it to spread bigotry
I am progressive myself and support human rights and LGBTQ+ people
Arabic speaker here and this sounds like the most harmless statement of all time. I mean you’re right in that it was probably more about the emotionally charged concepts than Arabic as a language, but still, I think this is one of those “white people getting mad at other white people when the minority in question wouldn’t think much of it” things.
People often say that German sounds angry. It has nothing to do with the skin color or religion of the speakers. I’ve not thought of Arabic as an angry language, but I don’t think that’s a racist statement.
The Klingon language is entirely artificial, it was created to bring an aggressive and war-like alien race to life. You’ll find people referring to it as “Space German.”
