You're doing something most liberals do when they realize they're losing the argument; they start "grunting". Providing pushback in snipped, short sentences. Not really making a point but saying just enough to keep the conversation going. They don't want to say too much because they don't want to be proven wrong, but what they are saying is silly and half-formed. "Homosexuality is not against the law"...makes no sense to what he said to your statement that gays are being discriminated against because they can't marry the people they love.
Failure on your part
Using examples of relationships that break the law does not support your case against gay marriage
Society has established specific reasons why they won't tolerate polygamy, incest, bestiality or whatever other hysteria you trump up
They have yet to establish a reason where gay marriage harms anyone
The arguments in support of so-called "gay marriage" can all be used to support polygamy and incestuous marriages. The "specific" reason for outlawing the later is the fact that marriage exists for the purpose of facilitating reproduction.
But you already know that not to be true
Many couples who cannot reproduce are allowed to marry
Try again

then those laws can be argued to change as well.
keep all marriage laws out of govt that people disagree on and/or which don't apply to all cases,
and only keep the language that is agreed on as applying to all cases.
Instead of just FORCING terms of marriage through the state, which clearly violates the beliefs of many opponents,
give EQUAL option to REMOVE marriage from the state in order to correct the unequal access.
The issue should be to make things equal under the state, not to push one agenda or the other.
So if this means REMOVING marriage, so that it is equal, then just replace it with civil unions and leave
marriage and beliefs about it to the people not the state to decide.
