It's used like that on Facebook a lot. You're welcome to your opinion on correct use and interpretation of emojis, but that doesn't stop others from using them the way they feel is appropriate.
Idk that's how I interpret the thumbs up after I say something. In my mind it's comes off like a dismissive "that's cool". Like what ever I said isn't worthy of a text response. Idk it's a little odd to explain I guess
I think it means something very different in a work slack thread than a text chat with friends.
In a work context, it’s perfectly reasonable for someone to want to briefly communicate ‘go ahead you have my approval’ and not mean anything snarky by it. Yet if I’m messaging with my friends and they ask about going for drinks Saturday, and I say ‘go ahead, you have my approval’, that’s going to come off as pretty passive aggressive too.
Second, even if it was true (which I doubt), there are some things which should be ignored and someone believing this nonsense should not be coddled.
I'm very liberal, but this is just pure nonsense.
