>Would you want your kids to be shorter and physically weaker than you are?

As someone who eats meat, that's probably one of the worse arguments against vegetarianism/veganism I've heard. If eating animals is immoral, sure why not? If pillaging your neighbors makes your society better off, do you think a good objection to "maybe we shouldn't pillage our neighbors" is "Would you want your kids to be shorter and physically weaker than you are"?
