If you are too squeamish and sentimental to kill animals you should not be eating meat.
This was interesting, as I'm a lettuce muncher without a squeamish bone in my body. I would relish the chance to chase down, kill, and butcher an animal if I had to. I just don't have to.
And if you are too squeamish to work down sewers then you shouldn't use toilets
This was even more interesting, as a rare example of STW actually causing me to question my beliefs. This deft analogy exposes the weakness of the argument that you should be prepared to do something yourself in order to benefit from it.
I'm still not gonna eat animals till I have to, though.
