If everybody in the video consented to being a part of the video and had no problem with what they saw, I have absolutely no problem with this. I can see why people are angry about this, given the recent outburst of workplace sexual harassment that we've seen, and the fact that the leader of the free world admitted to committing workplace sexual harassment regularly. I can also understand why people don't think it's okay to make light of something like this; people who have experienced workplace sexual harassment are seriously traumatized. Some have lost their job because they wouldn't have sex with their boss! It's not something to joke about at all.
I don't have a problem with Kesler or the Ducks doing this but the backlash is partially justified due to the prominence of workplace sexual harassment.
