I totally agree Scooterwolf, not so long ago inter-racial marriage was taboo and illegal. Same scare stories went with that debate but it didnt end the world and we all just go on with our own lives once the laws changed, same will happen here.
Those against are in the minority anyway and in a democracy the majority rule so they will gain the right to marry eventually. People who are against it have no real credible arguement as far as i can see, it wont affect me or my life so why should i care who can marry who?
Live and let live as long as it causes no harm to others, which this doesnt.
