Somewhere in the world someone is doing something I wouldn't do, and someone else is doing something I would do. Yet, here I am typing away UNAFFECTED by either. I believe that we all have the right to make our own decisions - to love, to hate, to spend, to save, whatever - so long as you are not depriving me or others of their freedom to pursue whatever happiness this world has to offer not only is it not my business, I don't want it to be.
Here's a (by no means complete) list of things that anyone should be allowed to decide for themselves:
To have or not have children.
To marry the person they love.
To practice their faith.
To run for elective office.
To educate themselves.
To pursue happiness free from fear.
