I don't see any need to ban political discussions from this site. I visit it every day. I do not read every post. And some of those I do read, I click off because they're [1] more full of stupidity than I want to endure; [2] not a subject that interests me; [3] too poorly written to under stand without mentally translating it.
There is no law that says we must read every post, or that we must agree with everything written. Self edit. Assume some personal responsibility for what you read. This isn't high school or university where you MUST read assigned material. This is a voluntary association, and if you find a topic that makes you grit your teeth, skip it.
Liberals want to censor everything. Those on the far right love to rant and promote 'theories.' You do not have to read any of that, unless you want entertainment.
