> Instead, they want to hear that it is okay to feel said emotion.
That's not the definition the others are using, but this seems to be a game of whack-a-mole with everyone's different ideas about what it means.
That said, I think your definition highlights the problem: By telling someone it's okay to feel the emotion, you've implicitly endorsed the response.
The situations I'm speaking about involve people developing inappropriate emotional reactions that lead to self-harm. When they surround themselves with people who do this "validate emotions" game, they're implicitly gathering consensus that it's okay to react that way. The cycle continues.
It's clear that a lot of people have picked up this idea of "validating emotions" being virtuous and good, but some times what people need is for people around them to explain that their reaction is not actually appropriate or okay.

This tells me that you've not understood my meaning. One is not condoning or endorsing any behavioral response when they say the emotional response (which motivated the behavior) is valid and natural. They are distinct things and one does not necessarily follow or precede the other.
> their reaction is not actually appropriate or okay
I suspect we are talking past each other here. If "their reaction" refers to their emotions, that is not your concern; to think otherwise is wildly antisocial. If it instead refers to their actions and/or behaviors, you simply are not bemoaning emotional validation.
> That's not the definition the others are using
For what it's worth, imo this is included in the definition of "accepting" someone's feelings. You are saying "it is acceptable" to have the feelings.
