That doesn't matter any more. Look at Trump's claims about vaccines and autism. How many times has it been shown the study he cites is completely fake? How many discussions on here have gone over this same subject?
Witness Trump's comments about vote fraud. He says it took place but cites no evidence. In fact, when he filed to stop the vote recounts he explicitly cited no evidence of vote fraud taking place so there was no reason for the recounts.
I could go on but it's quite clear citing evidence, showing the facts and everything which is normally done to show how one side is lying, is no longer effective. Instead, the more evidence one shows the more they are shouted down. Why? Because showing evidence and facts hurts people's feelings. It forces them to admit they're wrong and in so doing makes them feel bad. Evolution anyone?
