On the subject of Intellectual Property, a lot of the radical anti-IP stuff entered the libertarian movement through a guy named Stephen Kinsella. He's one of the most toxic people in that community, going around astroturfing, acting childish, insulting, slander, etc.

His behavior helped solidify my theory that the most toxic an ideological person is, the more flawed their underlying philosophy usually is. It's like the idea that someone who uses violence has already lost the argument, however in this case, anyone who attempts to verbally has already lost the argument.

The takeaway being you should always distance yourself with movements that devolve into toxicity or violence, and also question if the ideas lead to that toxicity.
