Dennis Prager on women and sex

Dennis Prager writes, regarding the California Supreme Court's decision to strike down a ban on same-sex marriage, that:

The sexual confusion that same-sex marriage will create among young people is not fully measurable. Suffice it to say that, contrary to the sexual know-nothings who believe that sexual orientation is fixed from birth and permanent, the fact is that sexual orientation is more of a continuum that ranges from exclusive heterosexuality to exclusive homosexuality. Much of humanity - especially females - can enjoy homosexual sex. It is up to society to channel polymorphous human sexuality into an exclusively heterosexual direction - until now, accomplished through marriage.

It sounds like he thinks that female heterosexuality is so tenuous that it must be enforced by the power of law. Does he also think this is a justification for denying civil liberties and rights to women?

Ed Brayton gives a good fisking to Prager's entire crazy essay on this subject, showing that his arguments are very similar to arguments that were made against integration and interracial marriage in response to Supreme Court decisions.
