When I said "wrong thoughts" I was thinking politics - far left and far right, generally. But yes, also porn, copyright, etc.
1. Ideas that are directly trying to silence others or obscure empirical reality.
2. Ideas that actually can be said but are marketed as being "censored" or "counter culture" to give weight to a narrative.
3. Vague gestures to some other idea that is supposedly neither 1 or 2 but is unable to provide any evidence
I would love to add a fourth entry but in the same way it's inaccurate to assume this is 1 (Apple's "victory", apparently), it would be equally inaccurate to not categorize your views in 3 until you were able to provide specific evidence.
