You hit the nail on the head right there.
I dislike the upvote/downvote system. Its supposed to be for "This is good" or "this is bad". Not "This is good" and "I disagree with this."
You can disagree without something being wrong or incorrect. But the younger crowd doesn't seem to get that. Just like identity politics. You can't say "I dislike Biden because...." without someone jumping down your throat calling you a trump supporter. Like slow your fucking roll here dude, I can dislike more than one politician at a time, and just because I dislike something about a Liberal doesn't make me a Conservative. But to those folks its extremely black and white.
And once someone downvotes you and your post drops to 0 or less, you might as well delete it, because once one person see's that downvote, they assume there is a reason for it and they downvote you too. No one has to justify why they are downvoting or think you are wrong. There is no room for discourse. And if you try, someone will dig through your post history and then be like "well 3 months ago you said you said you owned guns, so you are obviously a horrible conservative and should go kill yourself."
