Going back to silly games:
If other people's relationships don't affect me and are therefore non of my business, I accept that as true and agree. As I don't personally want the 'right' to marry a man for myself, I'll vote no on such legislation when I can; this is coming from a father who's children would benefit from such a marriage.
Yes I make that choice for myself based on personal religious conviction, but it's my life and my vote so as per the 1st amendment I'm free to choose. In fact, you're legally prevented from stopping me.
