ABC "News" snowflakes butcher the grammar to ensure they don't accidentally "mis-gender"

Still think the Mainstream Media is even remotely sane?  Then take a look at the screenshot below, from the website of ABC "News." 

A man tried to set himself on fire.  But the lunatic liberal plotters who run ABC's website are all good little Democrat wackos, so they know that just because someone looks like a man, he may actually have declared that he's female.  If so, it would be a horrific breach of leftist political correctness to "mis-gender" a self-proclaimed woman, right?

The snowflakes don't even slow down to solve this one.

 

Of course: Even though all witnesses said it was a man, ABC's wokie snowflakes--determined not to mis-gender--lead the headline with "Person."  Singular.  Oooh, but now they can't say "...sets himself on fire" cuz again they don't wanna risk the 0.01 percent chance of mis-gendering xir.  

So to be safe, the snowflakes settle on the collective term "themselves."  Yay, snowflakes!

Except that sets up a grammatical conflict:  After ABC's woke snowflakes said "Person" instead of "Man," but then used the wokie collective form "themselves," do we use the singular form of the verb ("sets") or the plural?

"Hey, hater, you're just trying to oppress us with your so-called patriarchal 'grammatical rules'!  What's important here isn't your oppressive rules, but that a headline doesn't mis-gender someone!"
