File this under “deliberate but justifiable antagonizing.”  There’s an Uber driver who makes a hobby of trolling anti-vaxxers.  Excerpt:

When anti-vaccine activists gather in the shadow of the big black “Vaxxed” bus, it’s easy to spot the guy who’s there without an invitation.

He’s the protester holding a homemade sign declaring that vaccines save lives. He’s often wearing a T-shirt with the name of the polio vaccine pioneer Jonas Salk, stylized like the logo of a rock band. You might even spot him filming a lighthearted video updating his online followers on his quest to chase down the Vaxxed bus tour, which grew out of a controversial anti-vaccination documentary with the same name.

Craig Egan estimates he’s put 7,000 miles on his Toyota Prius subcompact this summer following the bus tour everywhere from the Pacific Northwest to Missouri. And no, he does not mind being called a troll. In fact, he embraces it. He even plans his T-shirts to be as annoying as possible.

“I enjoy being, frankly, a pain in the ass to anti-vaxxers,” Egan told STAT last week from the road, where he was trekking from one Vaxxed event in Dayton, Ohio, in pursuit of another one in Lansing, Mich.

If there was ever a group of knuckleheads that deserved some trolling, it’s the anti-vaxxers.  The legacy of Edward Jenner and Jonas Salk comprises, probably, the single greatest advance in health care since sewers and clean water.

The anti-vaxxer nitwits are of a piece with the anit-GMO crowd.  Unlike the anti-GMO crowd, the anti-vaxxers seem to have adherents across the political spectrum – even President Trump has expressed anti-vaccine sentiments, although it’s not clear whether or not that was a campaign tactic.

It’s rather sad, but the world has no shortage of nitwits.
