Thorolfr:
Laws on “alienation of affection” don’t make much sense to me since anyone who commits adultery should be responsible for their own actions. No need to blame someone else beside the cheating spouse as if they are not able to control themselves. As for your first example, I don’t see why same-sex couples shouldn’t be able to sue for the same thing since sex is also an important component of their relationships.
I think you can see that the Church does not want to find itself in the position where teaching that homosexual relationships are not marriages and homosexual activities are wrong could be a civil offense.
You’re saying that same-sex couples should be able to sue for loss of consort, but people here are saying that marriage isn’t about sex. Someone needs to make up their minds about what marriage means. Does it have to do with sexual relationships that society has an interest in legislating, or doesn’t it?
