jamescostian has addressed the point well enough, but to add more to it, there are many ways to state an opinion, but tchaffee chose a very authoritative one, and when you claim something as true with neither evidence nor a good mechanism exploration, I believe you should be called out on it, because way too many claims like this are being made these days and people often end up believing them because they don't stop and think about how poorly the claims are actually supported.
