I never said anything about political pandering, and I'm not rejecting expertise. I am just offering an explanation as to why SOME people drag their feet when things move and change. People presented the previous info as cold hard facts that could not be questioned, and anyone who wanted to talk about it needed to just STFU and quit being a science denier. Then when we learn more and things are different, you want to throw your hands up and say "well we didn't know as much about it back then." So why present it as cold hard facts that can't be questioned? Science is about questioning things and being challenged. It shouldn't be used as a hammer to beat over someone's head if they want to discuss something.
