Wolf,
Just like you are not allowed to make yourself bleed so are the goim. And any exception like going to a doctor also applies to both.
The fact that goim used to do blood letting doesn’t negate the fact that they are forbidden to do it according to our religion.
So, basically, he’s required to go around looking for a Jew to say “please kill me” to?
No, he doesn’t have any requirements, we do!
