The problem with RW opposition to no-fault divorce and gay marriage is that it fundamentally misses the point. They are going to scream it was because of "feminism" or "degeneracy", but actually, the only reason this is the case is because John Calvin declared that marriage is not a sacrament in 1536.
If marriage is not a sacrament, then that means religious authorities have no connection to the institution of marriage. Because of this, marriage is now a "civil contract" bound to a law. Judges, not priests, make the call.
To understand what this means take the Puritan colony of Massachusetts and compare it to Ireland in 1994. Under a 17th century Calvinist dictatorship, divorce was legal and defined. Meanwhile in a western country 30 years ago it was illegal. The only reason? Differing Christian sect, and keep in mind we are talking about the Puritans here.
Transferring the domain to marriage from religious dogma to civil law means that the latter can be changed and fought by lawyers, in come divorce. In comes gay marriage. If you are raised with the belief in religious dogma there isnt any changing it nor debating. Marriage as a civil contract leads to this, which ultimately came from Protestantism.
Blaming divorce epidemic on women isnt't wrong per se, but it misses the point. The enemy is Calvinism. Period.
