I'm not arguing about the moderator, I'll go ahead and take your word for it that she sucks. It's just annoying to watch these apparently "meaningful" debates that just have people dropping facts and numbers and watching them bicker about it on stage pointlessly. It's a good point you make that if someone fact checks in a debate, the presidents can only be like, "lol nope". So perhaps in that way it should be left alone, but without that its just a lot of fluff, and as soon as I get on the internet there's just all this mud being slung on the falsehood of all these things that are being said. I hope that helps you understand my sentiments on it, I honestly don't know what is best I guess, I just know that there are probably a lot of morons who don't get on the internet or care to check the validity of things (maybe there are some who also can't do this).
Perhaps I should refrain from engaging in political topics here, it's easy for stuff like that to get ****ty, just as you describe.
