What is the distinction between having an opinion and having knowledge? Is one more valuable than the other in life?

Well, maybe this can help clear up the distinction for you.

Do you believe in the LGBT movement to be recognized as girls becoming guys and vice versa. Whether your answer is yes or no, that's your opinion based on your personal beliefs.

Now

Can a person…any person manipulate their DNA to eliminate either the x or y chromosomes from their bodies and truly change gender?

Of course not. Right?

That's knowledge based on scientifically proven facts.

Now before you go and start questioning all your personal belief systems….it's perfectly ok to have your opinion still. The facts don't invalidate your opinion. They just prove it either wrong or right and those outcomes really only affect those within that community and not necessarily offend or become enthusiast to that particular belief and affect your opinion.

Understand?

Opinions are what we have until knowledge proves it one way or the other.
