I just noticed your username and it made me feel so extremely disgusted that I am going to block you, just to never have to read it again, nothing personal though. Also, with such a username you are not in a particularly good position to criticize others for their choice of words imo.

You: Insult a group of people that had no power over their condition
Them: Insults no one, has a ridiculous username
Your reaction: You’re disgusting! I’ll block you!
Even not being a native speaker you should know the difference here.
I fucking love the internet
