This is what I really hate about the people who say "Well, we just didn't know back then" or "We didn't have the evidence we do now" or, the worst one of the lot "They didn't do enough to convince me".

We knew. The evidence was there. And excuse me princess, if you think it's our job to personally persuade you to the correct position, how about you save all of us some time and just don't opine on a goddamn thing. Because if you're not willing to put in the relatively easy work of looking at the available data, you clearly aren't ready for the much harder work of correcting the issue.

I'd even accept, "Well, I was lied to and I fell for those lies." But I've not seen one person go that route. Probably because the entities that lied to them then are still around them today. If you were also a member of certain think tanks, finding out that they were perpetuating lies, kind of calls into question everything about them. Including your perceived status as a thought leader. So the institute can be wrong, but it can't be deceptive. And if the institute is wrong, it's really the fault of everyone else for not doing a good enough job of being logical and rational.
