Starting a thread about CardsChat on 2+2 might not necessarily get you banned. It will more than likely get your post/thread deleted however. Not the case here, it is embraced.
Different forums, poker or otherwise, all have different rules. Some are more strict than others. For instance, there are some forums that absolutely do not allow any posts regarding religion or politics. Those types of conversations tend to get heated, and will cause tensions between its members.
That remark was really uncalled for. If you don't agree with a person, then say so. There is no need to resort to name calling. BTW, that remark is against the rules here and is an offense that could get you banned.
