Hitler's supposed (debatable) vegetarianism was, if factual,
apparently for health reasons.  Not about killing animals but
concern that they were killing him.  There's a discussion on it
at:

arian.html
just in case anybody's interested.  I've never been sure what
the point is that people are trying to make with this.  And
believe me, there are people who just love saying this to
vegetarians.    Eating meat upset his stomach.  What is the
significance?

Cheers,
