The definition of 1 + 1 = 2
We all know it, it's not a theory that needs to be proven, it's not something that can be modified, that's way it is. The point is, that's the same with 'marriage', where a man and woman creates a family and might create children. That's what the definition of marriage has been.
LGBT are trying to change this definition and they claim other people cant vote on this? Why not? This impacts everybody, not just benefit them, it could harm the children too!
If we were to change the definition of 1 + 1 = 2(real marriage) to include 1 + 2 = 2(gay marriage), what about 1 + 3 = 2(multigamy?) or 1 + n = 2?(what ever)? That's discrimination.
