Freedom of speech is utter freedom. No holds barred. No bans. Nothing.
Banning of books - whether it's LGBQ or the Quran or 1984 - is wrong.
Books are truth within their own tiny microcosm of reality.
It is us, as the individual, to determine if we personally perceive them as truth.
In summation, freedom of speech must remain totally free. (But that doesn't mean one should be "a dick!" lol)
