Freedom comes with a price. You have rights but you gotta play by the rules. Properly established, that protects everybody's rights.
I know how it is, I can't post a lot of stuff I'd like to post. So we're all stifled. It's annoying but it keeps us from killing each other, figuratively.
You just have to live with the limitations on CB and get on your soapbox somewhere else. If it's your domain, you can say anything you want. But when you're in other people's space, you can't do that. Don't let that run you off, it's not worth it.
