I think there is value in people like Stallman existing. I disagree with him in a lot of regards, but I think it's important for people like him to shift the "Overton Window" of software copyright a bit closer to FOSS. He's a disagreeable bastard, I'm not even sure he would dispute that, but a part of me does respect the dedication to the cause.

That said, I almost always use BSD or MIT licenses for my personal stuff; sometimes I use the Eclipse one because that's the default that Leiningen gives me for Clojure and I can't really be bothered.

That captures my sentiment exactly and GPL is always the choice for me.

For the last 30 years a strong belief in anthropogenic global warming has been polarizing too.

Sometimes appeals to moderation are valid, but I think sometimes it is entirely the wrong thing to do.

Idealism retards the growth of most good ideas. I suffer this daily but it is an internal struggle and I structure my idealism to minimize the impact on others.
