I agree with jmizzle and am fine ignoring the OP, but...
To humor all people that say that people are born that way, Autistic people are born violent, that doesnt mean that they have a right to be. Life is about doing something with it, not just making excuses for everything saying its out of your control.
So why should being born that way be an excuse, if we still say autistic people arent allowed to be violent? Also, an in-law who is mentally slow, got sent to jail on child molestation charges, because he didnt understand something he just said, not did, but only said to a boy was wrong.
So to answer your question, why should that be an excuse?
Blue Priest, while I normally disagree with what you say, I can at least respect it. However, I find this totally unacceptable. For one, you clearly don't understand autism, as your blanket statement is as ridiculous as it is wrong. I would hope a christian could muster some more compassion for one of god's fellow creations. Second, at least in the US, if your in-law truly has a condition, he could have been treated differently under the law, because we recognize that it is NOT an excuse and he should NOT be treated as the same as someone who knowingly made the same decision.
How about I laugh at your inability to cope with the world because you hide behind an invisible sky wizard as
your excuse? How much responsibility do you take for your
own life when you say everything is out of your control and part of "god's plan"? Why is it noble for you to give up control to a god you can't prove, and yet for people with a medically valid condition that everyone can see and agree on it's an excuse? Honestly, the hypocrisy here is overbearing.
