And fwiw, if your disapproval of some group or action is based solely on dogma it might as well be hate, and it certainly does a lot more to encourage malicious discrimination than backing your disapproval with some meaningful/rational explanation.
I get what you're saying, but rational is a pretty subjective term. The issue I have with this reasoning is it suggests humans can "figure it out", which has caused plenty of hatred and pain in the past. I for one am not smart enough to figure anything out, and the bright ones come to different conclusions anyway. What about spiritual confirmation, real or perceived? Is there any standard other than self-righteousness?
