Childbearing is optional in marriage, that isn't an opinion, it's a fact.
"The main thing is mutual attraction and sexual satisfaction. Those are the basis of the argument for gay marriage.
Well no, that isn't the basis of the argument for gay marriage. They claim, as a basis of their argument, that it's about equality and civil rights. It still doesn't make any sense, but that is the basis of their argument.
...which makes it inevitable that this country will not — cannot — see anything wrong with same sex marriage....
I would say it's more that people don't understand the basis of the homosexual argument, and therefore don't understand how to dispute it with rationality and reason.
Congratulations; you are now an advocate for gay marriage.
If marriage is going to be re-defined as unmoored from childbearing and motivated entirely by mutual attraction, there will be NO reasonable basis for denying it to same sex couples. The liberal view of marriage, accepting of contraception and divorce, is entirely mainstream in America today, and gays are absolutely correct in asserting that in such an environment there’s no reason apart from discriminatory animus, for arguing that same sex couples should not enjoy equal access. This was baked in the cake when the Protestant churches caved first on divorce, and post-1930, on contraception.
If you have a rational argument against same sex marriage — or better still, what REAL marriage is — let’s hear it. But do not kid yourself that you can gut marriage of its essential orientation to childbearing and still retain an argument that can stand up.
