Here's the thing. If you're into social justice, as in you've made it something of a hobby, these videos will be just fine from your perspective. If you spend your time thinking about social inequality and political correctness they'll seem inoffensive, definitive, immanently relevant, and even obvious.

If you don'tspend your time thinking about these things, this sort of thing seems standoffish, condescending, completely irrelevant, preachy, and annoying. "You guys should really check out these videos on harassment" reads as "I think you guys are assholes and need a video to tell you not to harass people". Armchair social justice advocacy is basically a rogue HR department and isn't generally considered to be a good thing by the communities who fall prey to it. Often because it's in the form of someone who has only a peripheral connection to the community if any at all imposing their standards of behavior.

At some point along the way a group of people decided that tolerance means thinking and acting exactly like them. Whatever they want to call it, people tend to frown on actual intolerance.
