Coming from someone who feels this topic is beneath them:

I would never touch it with a ten foot pole.

It isn't surprising that you believe that:

...the response you've gotten here is levelheaded and thoughtful.

While I appreciate people's comments expressing their approval about questioning, if you read the comments, few have actually watched the video and engaged in the topic. While others have done exactly what I tried to warn about in the post, jumped to conclusions rather than to read/watch and then join the discussion with an open mind. Quite honestly, from my end, it feels like a bit of a condescending tap on the head.

To me a positive discussion would have been for people to engage with the parts of evidence mentioned in the video and then explain with other evidence why they disagree. That'd have been way more productive for everyone. But since we have different points of view on the topic, and the fact that you only joined in when you felt your ego had been poked, it doesn't surprise me we'd also perceive the response differently.
