No one blocked. And while a few times, a few folks had my temper up, I could not name a single person. Even half the names on here, don't mean anything to me. There are about half a dozen people whose name/ID I recognize. When I see a name I do not recall, I am always surprised to see they have thousands of posts more than me.
There really isn't that much debate on this site. Most are in fact conservative. So, without the liberal whack jobs here like on FB, this site is tame with like minded folks.
