Avatars really aren't that large people shouldn't be wasting employer/public resources here anyway, NSFW threads should be marked as such our have their own section, or are you openly advocating censorship?
I'm advocating property rights.
No you're not. No one is disputing the rights of the forum owners to do what they want. You are yet again advocating the suppression of content that you, personally, don't like. Whether you do so by lobbying the owners of a forum or the leaders of the government, it is your belief that you can and should actively try to restrict the expression of others.
