Unless they looked into the discussion, who would believe the Pope isn't Catholic? Or that a frightful percentage of priests and bishops are pedos/satanists? Or that governments construct intricate lies about many things like global warming? Or realize that people in power want most of the population dead? Useful idiots always decry opposition to the narrative before looking into it and say stupid things to support what they think they know. Thinking people look into an argument and understand both sides before opening their mouths. And even then, they don't mock or scoff, they ask pertinent questions to be sure they are getting all the information they need to find the truth. Somehow, the proper approach is rarely employed when it comes to flat earth.
