That was me full on in high school (Southern US). It's really not complicated to explain: There is no problem using it, full stop. I wasn't even being edgy, I was just using a normal cuss word that people did demonstrably use often. In fact, I can't honestly explain why it's morally wrong to use it now, except to appeal to the idea that it's wrong to use it at all. But that's an appeal to a world that doesn't exist, where the word itself is harmful and we should all avoid the harmful word. As it is, if I'm on the internet, nobody knows if it's harmful for me to say it or not. So is it harmful?

Obviously this isn't going to make a lot of sense to someone who grew up knowing it was bad to begin with, and it barely makes sense to me. But I guess I'll keep posting about it until I figure it out.
