Plus, the left is far more likely to hold people accountable and own up to mistakes. Remember Al Franken? When was the last time a politician on the right did anything other than double-down or change the subject when faced with a scandal?
Eh, the phrasing is a bit on the libertarian side for my liking (are we still doing phrasing?), but I like the sentiment. I take the "social contact" view of the Paradox of Tolerance, so speech and rhetoric that deprives others of their rights should not be protected, IMHO.
Plus, this is designed more as a personal code of ethics rather than system of government, so I'm not really too worried about "enforcing" any of these. And since I personally don't see a conflict when it comes to limiting the speech of others if it is inciting violence or encouraging discrimination, I think it's ok the way it's written.
But hey, to thine own stuffself be true. Write your own version if you like and share it around.
