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

The suffix -ism does not imply hatred; it merely denotes an attitude.
Consider communism, nationalism or patriotism.

The prefix mis- and suffix -misia carry the required meaning.
Misogynist = hater of women.
Homomisia = hatred of homosexuals: a much more appropriate word than homophobia which simply means fear of them.
Religiomisia is a word awaiting its time.

The term most widely used for this is not a single word. It's religious discrimination. Religious intolerance is also used.

Sectarianism is bigotry, but not specific to religion. It means any discrimination or hatred arising from perceived differences between subdivisions (sects) within a group, such as between different denominations of a religion, class, regional or factions of a political movement. It does carry a connotation of religious discrimination because sects are associated with religion (a sect is defined as a body of persons adhering to a particular religious faith; a religious denomination) but the broader connotation of sect is a group regarded as heretical or as deviating from a generally accepted religious tradition; a Christian denomination characterized by insistence on strict qualifications for membership, as distinguished from the more inclusive groups called churches; any group, party, or faction united by a specific doctrine or under a doctrinal leader.
