Not at all. It's the kind of right that should most be enshrined because what you deem "jerkish" behavior may be entirely different than what others deem it.

It's deliberately rude to tell Muslims their religion is farcical, and that following a false prophet known for extreme violence and pedophilia is not compatible with modern Western society. In this light, it's most definitely not strange to want to fight for your right to be deliberately rude to someone. Religions and bad ideas should be mocked.
