It's like the way that millennials communicate with emoji I'm GenX and not a millennial. I don't see anything wrong with using some emoji as part of my language. I already speak a language (English) which is some bastard child of French, German, Dutch, Arabic, etc. I'm happy to add a (poo emoji) when it's appropriate.
Emojis are fine. But I remember the first times I started seeing "LOL" and "ROTFLMAO". And I realized that the person wasn't really laughing, but they were quietly typing that on the keyboard. If you think about it, before AIM and online chat (way before texting), people hardly ever faked their emotions so much. I mean, you could fake a small laugh, but you didn't outright say that you're rolling on the floor laughin…
In the late 1980s terms like LOL were used on BBSes and on Usenet. Perhaps you just aren't old enough to remember that? :-)
