I liked the talk and was about to post a link to it in the $dayjob slack, but this threw me off as well. Still watched it to the end, and I still recommended it to a friend (along with the Youtube channel of the "Software should work" conf), but I'm saddened that the talk paints Christianity as something that is inflicted upon you and that you should strive to get rid of.
It's clear that he had a bad experience, and I'm nobody to tell him what to put on the slides and what to leave out, but my impression is that there are lots of believers out there who do cherish their faith, experience it as a very positive force in their lives, and draw from it the power to make the world a better place around them. Speaking for myself, I'd say faith has been a net positive so far in my life.
