I skipped the gay marriage issue only because I ran out of characters.

At the present time, our SACRAMENTAL theology of marriage does appear to presuppose a man and a women with a view to procreation. I can conceive of a distant future when that could change. 

But this is not the question on the table for Catholics at this time. In terms of today:

1) I utterly reject our current magisterial teaching that homosexuality is an intrinsically disordered state, and that gay sex in immoral, and thus gay marriage as the context for immoral gay sex is, therefore, immoral. 

2) I totally support gay marriage as a secular institution, and am totally ashamed of Catholic resistance to governments legalizing gay marriage.

3) Given the above, I would very much like to see secular gay marriages in Catholic churches with the addition of an appropriate blessing. 

But VVV, I don't understand why you addressed your questions to me? They do not appear to have arisen out of any particular comment.
