Why do you think they can't explain it with their own words? What's the point of trying to write out an explanation of why a claim that has been debunked so many times is wrong when they don't know why you think it isn't or what arguments you may have heard before that you found unconvincing? What do you think justifies such an expense of energy? Or do you think any video can be condensed into one or two sentences that are sufficient to convince anyone holding opposite views that they are wrong?
