What you're doing is called tone policing and it's not helpful. Would the post have gotten as much attention if the poster had been meek and polite? Probably not.
people are allowed to have opinions on how other people express themselves. where does the policing come in, I don't understand
The policing comes in when the top comment criticizes how the poster presents themselves instead of addressing the content of the post.
I think we are in agreement here - this post is an emotionally charged person venting. I don't have any problem with that, but maybe there is a better way to vent than on the discord support page. If you want to actually effect change, this is not the way to do it.
