Reason and logic apparently don’t count for anything under leftitst dogma. This is what people are telling you when they want you to reference a Peer Reviewed paper. It makes no sense. You can go to google scholar and search literally thousands of pdf’s, representing hundreds of thousands of science-worker manhours, and hundreds of millions of dollars of wasted taxpayers dollars but thats not going to resolve any controversial issue if at first you decide that reason and logic don’t matter.
Always its reason that helps us decide whats wrong and whats right. But the leftists have decided that the outcome of reason is not to their liking and they have therefore decided that only sentiment and wasted stolen money counts in science.
