Not that the headline isn't accurate. But anytime an article uses loaded words like 'slams' you automatically know it isn't going to report just the facts of what happened, and I usually just don't read articles like that.
If a headline is click bait, you can't really expect the rest of the article to be honest and straightforward either. If that's not convincing enough, you can always find a few websites that rate news sites and see what they have to say about them.
Journalists write articles, editors write headlines. These two roles have different motivations, but it doesnt mean a editor making a clikbait title detracts from a reporter's journalist integrity.
Reporting can 100% be clean and fair even with bad headlines.
This article was pretty much exactly what its headline said. It is mostly extensive quotes from Shawn Fain, which could aptly be described as "slamming" Trump.
Look at this guy who missed the absolute beatdown the UAW president put on Trump. Ran up on stage mid event and hit Trump with a clean double leg takedown
