if you're taking a serious amount of offense to what's being said, then just walk away. discord has the option to deactivate your account, leave discord groups, and block people. if you're getting harassed on lotc then there is an option to log off of the server. you're not being forced to stay.
don't use lotc as an escape, seriously. don't let yourself grow too attached to the server and depend on it for some sort of happiness you may not find irl. if anything it'll make you feel so much worse if something happens to you here and you expected everything to be all sunshine and rainbows, which is what seems to be happening right now.
and just remember it's all online and chances are you will never meet a single one of these people irl. so who cares about what they have to say now
