Yay to small government!
And stop it sith the paranoia. "leftist" sites are regularly shut down or demonitised. It's all to do with money - what the advertisers want. If they don't approve of some bigoted racist liar who breaks laws, - but you do - then your problem is with them.
A fairer conclusion is companies tend to ban "more risky" stuff. You only think it's only right wing stuff because you don't notice the rest.
