Consider what kind of books are being banned from American libraries. It's books portraying trans and gender-nonconforming people in a positive or neutral light, not books calling them "groomer pedophiles". It's books telling American history from the perspective of America's exploited minorities, not books calling for ethnic genocide or pretending the US actually upheld the principles of freedom and equality it was allegedly founded on.
To support censorship, especially state censorship, is to support the powerful in imposing their version of the truth on everyone else.
