I was somewhat inoculated against the pipeline for two reasons:

1. I was in my 20s when I finally stopped going to church and had enough perspective to be skeptical of the anti-feminism content.

2. By the time I started watching atheist YouTube videos the split between left and right was well-established, so it was easy to filter out the culture war stuff.

That didn't stop YouTube from recommending Carl of Swindon's channel every chance it got.
