> There is no way to turn this part of the feed off.

Unfollow everyone, and you don't get sucked into interacting with the facebook feed. Use it for Messenger, groups, and events. I've been doing that, and facebook is a perfectly good communication utility without any of the grief.

Honestly, we as users should demand a simple switch that entirely disables the feed. It turns facebook from a socially messy skinner box into something benign and generally quite useful.
