Huckabee opposes Trump's cuts to the NEA

By the way, something I just don't grok...

On a Twitter link to this story, there are a bunch of comments sneering at Huckabee for taking this position. Mind you, they aren't people who disagree with the position. (I can understand why those people might sneer.) No -- these are people who, like me, don't want to see NEA funding cut. Like, here's an example:

"why is Mike Huckster pretending to care? He sold out low-income children and their families a long time ago. #Hypocrite #FakeChristian"

OK. As I noted above, I was surprised (pleasantly) to see Huckabee take this position. But my reaction is to applaud, and think "good, we need allies on the right on this issue" (and other issues). We're far more likely to save NEA funding if we have some bipartisan agreement on it. Right?
Maybe I'm missing something, but I don't see a nefarious political motive for Huckabee taking this particular position. It sounds like he means it, and means it for good reasons, at least to me.

So I'm confused. Genuinely confused. Why, if you agree with the position he's taking, would you want to sneer at him and put him down for taking it?  It's not like applauding him for taking this position means you have to applaud everything he does or has ever done. Of course it doesn't. You don't have to vote for him or give him money or send him a Christmas card.  Hey, you don't even have to applaud him for doing this if you're not so moved.  But why on earth put him down for it? Sneer at him when he's doing something you don't like! Or at least, that's my reasoning.  But this -- well, call me naive, but I agree with what he said and was glad to see him saying it. Now, if we can just get more Republican congress critters saying it...

This is a phenomenon I've seen before, by the way, on right and left. And it mystifies me every time. Anyone want to 'splain?


ETA:

By the way, I do fully understand sneering at someone who speaks piously about helping poor people as they are in the process of cutting programs to help them.  Absolutely, sneer away.  But here -- let's say at the same time Huckabee is arguing for NEA funding, he is advocating cutting school lunches for poor kids.  I could see calling him out with "if you care about poor kids, you shouldn't favor cutting school lunches, which for some might be their only real meal all day."  Better yet, call his office or write him a letter explaining the inconsistency, and asking him to support school lunches.  

But the comment above doesn't do that -- it just sneers at him for advocating NEA funding.  That's what I don't grok.  It just seems useless, nasty, and counterproductive to me.
