Things are different in other places dominated by other ideological groups. But here in the USA the only people I know of to make a concerted effort to get rid of books they don't want anyone to read have been Christians.Christians don't desire to ban books just because they don't like them. They typically desire to ban books that they believe are evil.
You might get the occasional crackpots, but the only committee I have known to go the government and make a case were Christians. And the only big book burnings I am aware of are Christians burning Quran.
