> It’s a good idea in theory as long as it’s not a excuse for right wing cranks to promote nonsense conspiracy theories and then complain about lack of free speech when their offensive nonsense is criticised.
I think that reads better without the "right wing" in there. I'm not sure Piers Corbyn is right wing, for example, and he has promoted several conspiracy theories, e.g. around Holocaust denial, climate change denial and Covid denial. He seems to like to denying things.
