Off topic:
It bugs me when people say
"You've never done this so you do not know, and you shouldn't talk about it." .... Or anything along those lines.
If it has happened to you, then of course your opinion will change. If everybody that talked about abortion (for example) has been raped then there wouldn't be any argument.
People need to see everybody's opinion and take what information they can from each person. They can sort right from wrong.
If you don't think any differently, then good, but you still need everybody's opinion to think that way.
So don't ever think 'It has never happened to you, so you shouldn't be giving your opinion on it'
Because that's basically what you think when you say "you don't have kids, so you don't know" or "you haven't been raped, so you don't know'
I can't really think of the words for what I'm trying to say in this long rant.
Your opinion is changed by everybody elses opinion. If you ever tell somebody that they shouldn't have an opinion or a say in something, then you're telling yourself that YOU shouldn't have an opinion. We change everybody around us, and you and I change them. No matter how small of a change that is, with billions of people in the world it adds up fast.
