Lemmy isn't a place for debates and arguments. If you don't follow the direction of the topic, don't bother inserting yourself into the conversation.
You need to be nice and supportive of whatever is posted, else you're going to have a bad time.
Read their code of conduct and you'll find that it's a moderator's discretion to ban anyone they believe is disruptive, regardless of the rules.
So unless a moderator goes on a deranged banning binge, you're automatically in the wrong.
If you can't accept that, i suggest you make your own instance, with blackjack and hookers.
