Protecting marriage means keeping its male/female aspect. Same sex marriage introduces a new standard of gender segregation to marriage where before it was always gender diverse.<LOL!!!! How does one "protect" marriage?? And what, exactly, is attacking marriage such that I needs protecting?? A person can grandly declare that pies need "protecting", too, but unless he or she can accurately define and describe what that means, they're pretty much just making up craziness, aren't they?
If you love integration and hate apartheid; keep marriage male/female.
