Is there a word for hate against religions or a specific religion?

Well, to have no feelings toward religion or to not agree with religion is to be an atheist. The hate of people o a certain religion is another story for example, the hate of Jews is called anti-semitism.

A bigot is a term for someone who hates people that arent their religion.Also prejudice or ignorant might fit so would intollerant or unaccepting.
