I actually know people who are still working on refutational evidence bombs like that. The problem is that actually finding sources and addressing his points in all their "but I really meant" vagueness is a huge piece of work, and people have day jobs. In the meantime, his shit is out there. If it's ok for anyone to read and agree with it without going through to confirm his "facts" and "citations" on the spot, then it's equally ok to read and disagree with it.
