It's not the taste that causes them problems. It's the lack of hormones they lose and are not replaced by the hormones in meat. It's why so many vegetarians are pacifists. They have no hormones left for aggression. They could (and are by their views) be easily led to slaughter because they don't know how to be aggressive anymore.
You see that so much in today's society. It has nothing to do with meat or hormones. We are breeding the 'toughness' out of our culture.
Most people today could never handle the hardships of 50 years ago.
Like Rome......
