Gay marriage does not hurt children but abolishing marriage would. It would be one step towards making it less and less sure that children will always have their mother and father, and their property, around.
I don't understand why. Possibly you misunderstood me: I was arguing for abolishing legal marriage, not abolishing the cultural institution of marriage. I am not legally married to my wife, we have a 5 year old son and everything seems to be ok.
It does not make much of a difference. In the jurisdictions I am familiar with, cohabitation esp. with a child is practically interpreted as marriage, such as in case of separation commonly acquired property gets split etc. Let me ask, precisely what aspect of legal marriage you object to? Because there is a chance your cohabitation already has that legally.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
