'I literally did a complete 360 and could care less about how people use a language.'; That's all my pet peeves in one sentence. They come across as 'ignorant' as if the speakers aren't aware of what they're saying. Otherwise, I believe language to be an ever-evolving entity. While we can define its current usage, trying to solidify it would be a fool's errand.
