In the discussion with Jack Dorsey on the Joe Rogan podcast, Tim Pool had a good point: some of the rules are intrinsically biased on one side of the political spectrum.
An good example is the rule against misgendering. Twitter forbids referring to a person using a different gender than the one that person choses. E.g., you have to refer to a male-to-female transgender as a "she".
But to conservatives, referring to someone using a gender other than their biological one is the definition of misgendering.
This is a purely ideological take, and Twitter chose the definition of one side over the other. Then they can apply it "impartially to all users", but its the rule itself that is not impartial.
