Im not talking about raising children in a gay relationship. In fact i said in an earlier post it was not a reason for or against the gay marriage argument. Its a completly different issue.

You don’t seem to get that socially and legally, marriage and raising children are intimately related.
Again not part of the argument. Marriage is not a pre-requestit to be allowed to adopt.
No, but it makes it much easier to adopt!
Homosexual behaviour in general was comdemmed. Now that it is accepted by society and most people see that it is not detremental to society as a whole. Their is no reason that homosexual relationships cannot use the same civil term of marriage that the rest of us do. As the OP stated. We are not talking about the religious institution of marriage, we has already been dumped with the emergence of the Civil ceremony.
So call it a civil ceremony, not marriage.
It is not down to me to provide sources that homosexual marriage is good for society. If you are wanting to discriminate against people its down to YOU to back that up with facts and studies. I do not have to proove that all men are equal and deserve the same rights. You definatly have to prove why they do not.
Double

You call it discrimination. We call it a societal norm, supported by natural law, religious institutions and thousands of years of success. We do not need to “prove” anything.
The OPs implication that Marriage can be thought of as purely a social issue, not religious, is fallacious. Religious people cannot compartmentalize their lives and their life views.
Seems like there’s not a whole lot more to say about it; religious will have their views and secularists theirs.
