There's nothing wrong with /pol/, but you shouldn't make off topic posts about politics on unrelated boards. It's obnoxious and if you actually care about what people think of your board, it gives you a bad reputation. It's not that we care what you think, it's that you go about it in ways that make everyone dislike you. Act like an asshole, and yeah, people are going to want you to leave. Believe it or not, you can discuss politics without being a fucking retard about it.
