Celticsblog has been a site that has, all but for a short time, always been a community that discusses just about anything, including politics. As a community, we get to talk about everything and, just about anything, we want.
My advice is if you don't like the political talk, don't visit those threads. If you feel you can't do that there is the option to limit your access and not be able to open Current Events threads. Send a PM to Roy H. He can take care of that for you.
