I have no issue with the Same-Sex marriage. If they want to larp as husband and wife, more power to them. They'll probably end up divorced anyway.

Which devalues the custom of marriage and signals that such degeneracy is, at least, moderately respectable.

Homosexuality, to a certain degree, is something that will need to be endured because it cannot be fully purged from society. But even ‘soft’ institutional support for it is repugnant and undesirable.
