"
they always think they know what's better for you than you do. Take your nanny state regulations and bother someone without their own brain."
Do you think people should be able to own and have their own nuclear weapons? How about biological weapons? What about murder? Should that be legal?
If you said no, then you do agree there needs to be some "nanny state regulations". We only differ on where the line should be drawn.
When people "grow up", they realize that the general populace isn't too bright. The world is filled with nutjobs, idiots and crazies. People who are downright evil. People who are sociopaths. Letting the "free market" sort them out is a fairy tale for the young and children.
I don't mean to sound condescending or harsh, it's just that I was once a libertarian myself (in my early to mid twenties.) I came to realize what a horrible ideology it was and when you see people making the same mistake you made, you can't help but try to help that person out.
