Dave Sim said in his latest thing of his, 'when you're on the right track, you'll know it, but until you get there, you have to believe you're on the right track'. Interesting little conundrum. It's not easy.
The First Amendment says nothing about your getting paid for saying anything. It just says you can say it. I don't believe that if a corporation pulls all the money out of you or a network pulls their money away or you get fired, you're being censored.
