Akenaton, just for an addendum to you post....you said, "..probably most young heteros dont either, but around their mid twenties they wish to start a family....."

I would venture to say that females usually have more of a drive to have children then males...the woman comes home from the doctors, and says, "Guess what, Dear...." and the guy's silent fear is 'Aw shit, don't say your pregnant'...he waits..she says, "WE'RE going to have a baby!"
His first verbal response is, (with the fear that it might not be true), "Are you sure?"...."Really??..You're positive???" ..(gulp)..."Well, that's really cool".....

Akenaton: "In my view...and it is only a view, the drivers of the gay "marriage" issue are not homosexuals, who have other problems to address, but centre "liberals" with a chip non their shoulders."

THAT is correct!..However, homosexuals do not have the pair-bonding mechanisms and cycles that hetero couples raising their own children do, and they DO sense it, therefore, the 'push' to 'marry'!!!
(..and that is a rather 'inside' insecurity that they have, whether they can articulate it to themselves or not).
..and that is a FACT!

GfS

Now, does that seem like 'hate'.....or understanding?
