That's awfully close to "terrorists shouldn't have rights", and problematic for the same reason.
Again, figuring out which speech is worth suppressing is a whole other can of worms.
EDIT: note that Jones did have his speech suppressed, and this was done because his speech was causing people to make death threats against the sandy hook parents. I feel like we could classify Jones's speech as intolerant against sandy hook parents, and the same logic applies as for any other type of intolerant speech.
