If you want absolutely no ability to filter any content whatsoever (censorship) to exist for users and relay owners, then you by extension do want to subject people to child porn and other unwanted content. That is literally what you are saying. Your argument is faulty. You can't have freedom and also tell others what they must allow on their relays, networks, and devices. I am not "silencing" your viewpoint. I'm simply laying out what your point of view is and disagreeing with it.
You can run your own relay and so can the spammers. That's the historical difference that you're leaving out. You guys can have it! That doesn't mean the rest of us want to be involved and it certainly doesn't mean we must sink our ships just so you can be on it.
I even stated in my post that different relays and clients would disagree on where the lines are drawn and people would thus need to be somewhere else. You're not off the network under that model. You just may not be on my screen, where you seem to think you have an inherent right to be. You don't.
