I am not certain what model you use for reasoning, but if person A says "I never saw X" and person B says "I saw X on occasions Y, Z, and W", then they don't "cancel each other out," unless someone is lying. Literally the entire rest of my comment was not about what I thought I saw, but what people have actually done. E.g. I mentioned what conservatives in Congress have actually done (e.g. latest https://www.washingtonpost.com/news/energy-environment/wp/20...) and suddenly we are arguing about anecdotes and I'm accused of offering strawmen. Uh, no.
