I commend SL for starting this thread and keeping it going. Great work.

I would however suggest a title change, if possible.

Deniers/call-'em-what-you-will constitute a small % of the worlds population. Even in the US which is the most denial-prone country in the world it is only about 20% and that is tied to political/religious affiliation mostly.

It is long past time to simply ignore it as white noise. It is not the 20% that is a factor in the US, it is the tiny fraction of the 1% that control the congressmen. (oops, un-pc)

So it is useless to try to convince the 20% in the US. That won't happen anytime soon and will make no difference. The above-mentioned fraction of the 1% don't care what they believe. They are irrelevant. Better to focus on progress.

The title of the thread just encourages interminable 'discussions' that go nowhere and will have no effect on future developments. It is an invitation to come sprout bullsh!t.
