You can see this phenomenon here on Imgflip as well. Lately I've noticed that a majority of the right-wing users on here are at least somewhat active on a couple of other streams and make lots of entertaining non-political posts as well, whereas most left-wing users seem to dwell exclusively in political streams. In fact, the number of leftists on this website who post non-political stuff at least occasionally that I'm aware of can be counted on one hand.
