I hold a lot of stuff back in other corners of the internet. I don't and really don't want to here. People of like minds should be able to disagree civilly. If your friends don't challenge your understanding with conviction equal to your own, what good are they? And if they can't challenge you without flinging insults, they're at the least irrational, and they're certainly not your friend.
I think here, if someone has something to say, they should say it.
And then go flame commies on twitter to get the meanness out of your system if ya got to.
