Hello! While I understand calling people retards and telling them to kill themselves might be funny to you, but we are not in a MW2 match 13 years ago. I also understand that some people do not have any empathy for others, therefor those words just slide out in normal conversation. It offends some people and can make them feel much worse. Just because I don't want to be told to "kill yourself, retard" doesn't mean that I am soft, it just feels icky.
Now some people can't wrap their head around that fact, and it sucks to others that don't want to hear kind of language and demeanor being slung around like a "hello". At the end of a day, most people choose to play a server like this to relax. It's laid back and enjoyable. If I wanted to get screamed at by people with ear-rapey mics, I would go play Rust or CS:GO, where truly, most of the people that act this way belong.
Be nice, it's not that hard. This doesn't mean to entirely exclude all emotions or ways to "beef". If you can't be mean ICly to people without screaming slurs or telling them to kill themselves, maybe just disable VOIP or find another avenue to pursue that wish.
