BoingBoing is a bit of a lucky dip. Different contributors with their own opinions, sometimes posting an item that’s already been posted by another contributor. Cory is quick to express an opinion sometimes based on dodgy facts, but you could argue that sometimes it’s more libertarian than left wing. You don’t have to read or agree with everything written on this site, and you don’t have to self-identify as a BoingBoing reader.
As for the “Sassy Trump is mocking gays”, this has been discussed on BB before. Peter Serafinowicz said it’s based on Liberace, and camp has been part of British comedy from the days of Julian and Sandy in the 1960s (and possibly earlier). You don’t have to be gay to be camp, and not all gay people are camp (obvs).
