There is a specific user who has been here as long as I've been- Lady Deerheart. However, they've been active the entire time, where I didn't really start posting until the beginning of the Trump administration. That user posts a lot of liberal content in Politics and disables comments. They even disable comments on posts here, mostly because when they don't there's a lot, and I mean A LOT, of MAGA trolls who show up to comment.
So, when maga-chuds say all liberals disable comments, they actually means this one person.
