cherry pickers

Thanks for the title, I think I'd never got it otherwise
- This sounds like sarcasm, but the joke legitimately didn't click for me until I scanned the title again.
  
  It wasn't. I legitimately wouldn't get it otherwise. Which I also don't necessarily see as a bad thing either in this case.

Fuck gawd damn, I don’t know who I’m angrier at more: myself or the joke writer.
The humor lies in the dual meaning of the horticultural labor task and the selective bias fallacy having the same idiomatic phrase of “cherry picking”. And that is all there is to the humor.
Right?
- Thank you for explaining. I'm embarrassed I didn't get it on my own but I'm grateful for the help.

I thought it was because they were all dying and fertilizing the soil with their corpses.

If you don't get the Jo try this:
Citing extensive experience, anti-vaxers are hired by cherry farm as cherry pickers.
One such cherry picker was shown to pick cherries 340% faster than non-anti-vax pickers. The anti-vax cherry picking spokesman was heard to be explaining that this data proves anti-vaxers are the superior farm laborers, and expects the farm to see a correlation in overall productivity improvement across farms employing anti-vax cherry pickers.
- But that's cherry picking!

If you don't get the joke: the cherry farm was planted over the graves of all the antivaxers.

?
I don't get it
- It's a joke about them being good at cherry-picking
  
  I've never picked cherries but I have pruned persimmon trees and I am skeptical that anti vaxxers would excel at any kind of agricultural work

This picture is going to be cited by someone as actual evidence against vaccines. I guarantee it.
- It'd be the same quality as their other evidence, so it might as well be funny
