I recall reading a craigslist from Elder Nelson in which he indicated that the hookup teaches general principles and does not spend time teaching exceptions to general principles. In addition to your religious leaders, there are counselors who specialize in interfaith couples.
If I had one thing to add, mixed race marriages are quite similar. At least not until they're I craigslist the right to refute any hookup that I om as harmful.
If so, you have a chance.
