Pushbacks are countable in the context of a debate with both parties present. It’s fine to say “I have two pushbacks on this proposal” because those are specific, countable, contained arguments.
There’s also the nebulous “pushback”, which is used to describe general resistance to an idea or plan in an uncountable way. “The general’s proposal was met with pushback from the oversight committee”.
Getting upset about being corrected means you've got so much hubris as to think that you think you couldn't possibly be making any mistakes, or so much ego as to think you are above being corrected... or both.
To NOT correct people because we might "offend" them leads to a world of clueless idiots thinking they're infallible geniuses.... Crap. We're too late.
Since this forum has threaded conversations, someone can correct grammar at the same time that someone else is progressing the discussion, so I wouldn't have a problem with it here.
Well, okay, there's another time: If they're obviously being mean about it. But I think most people would dislike that, regardless of context.
Pointing out that "feedback" in uncountable is giving information on how to better match actual usage. A prescriptivist will agree with it, but so would a descriptivist.
Contrast this with "lion's share": traditionally, it meant "all", but nowadays is usually used to mean "most, but not all". If I convince someone that they should use it to mean "all", they'll be further from matching actual usage. I think that's what qualifies it as nitpicky and rude vs. just helpful.
