That's not my experience at all. The examples cited in the article ("president Obama wasn't really black") are, in my experience, the very tip of the iceberg. I don't have to look too far in LinkedIn comments to find people posting ... pretty politically-incorrect shit. It's more the asshole-uncle variety of shit (e.g. "I don't have gay friends because gay people always hit on me", or "I couldn't work for a woman CEO, they're not cut out for it") than the facebook variety (qanon/incohate rage at $phenomenon/etc.), but there sure is a lot of it.

I mean, it's an N of 1 so take it with a grain, but LinkedIn definitely doesn't seem like a bastion of civility or professionalism to me.
