Hey there, Hungry Cancer.
While we don't expect everyone to fully agree with the Universal Rules on the boards, we do expect everyone to follow them. We may not catch everything 100% of the time, but the rules are enforced for posters, moderators, and Rioters alike.
Your specific comment had a few offensive lines it it, specifically referring to a "rotten sheep's dick" and calling the moderation team "power hungry SJWs". While we accept and encourage constructive criticism, this doesn't qualify.
Further, comments like "it wasn't honestly insulting unless you have an SJW/Liberal definition of insulting and offensive" don't open up the door for meaningful discussion, as they set a hard line in the sand, and further violate our rules about bringing politics and social issues into conversation.
You're free to disagree with the action taken but, upon reviewing the situation, the removal is absolutely appropriate. If you want to voice your displeasure with moderation or the universal rules that's fine, but please do so in a more constructive, less politically-charged manner in the future.
Also, please note that you were not suspended in any way -- the comment was simply removed, and a warning was given against similar behavior in the future.
