Sarcasm wasn't the right word. Bait. The post is designed to deliberately get you annoyed/mad so OP can disingenuously come in and call you an SJW when he himself doesn't believe this.

Roiland is the giveaway, aside from being "cancelled", his audience has never been one of the circles you'd expect for the other three.

I would argue it is in exactly the same circles. Not all fans but there's definitely a large proportion of Librights who identify with Rick and see themselves as geniuses and would unironically talk about humans the same way Rick does.
