You should choose your interlocutors more wisely. If you have prior knowledge that he “acts crazy” during a debate, and yet choose to have a discussion with him, you are electing to converse with someone you deem insane, which is, in and out of itself, rather “crazy”, yes? The only reasonable explanation is that you do so for amusement, which is understandable, but it could be construed as trolling. You can choose to ignore him instead and avoid conflict that you *know* will erupt as a result of your conversation.I have many fans and I don’t check their ID’s.
