I would suspect that the previous poster means something along the lines of: The kind of posts that are so extreme that they're a significant reputational/PR risk to hire. No company wants to be flipping on the news and see their name associated with someone who's openly advocating for atrocities.

Or that create significant concern that they're unwilling to do their job responsibilities if it means working with/interacting with people who don't share their political views. More than a few people openly state things like that online as well.

I've heard of a case like that where they started fights in the workplace over their views and trying to sabotage others...
