Understanding

This is same for being openminded. Being openminded doesn't mean you accept every position or opinion but that you'd be willing to consider the position or opinion before making up your mind about that position. Rejecting an opinion or position is a valid outcome of that process even if something simple like I like to eat meat. If you ever have a conversation and someone attempts to use the same argument as above the reverse is a good response. If they "understand" that you why you like to eat meat, because it tastes good, then they should also eat meat. Letting a person get away with such a horrible argument doesn't do them or you any good and should be stopped whenever you can.
