Teen Gothic

For context, I am Gen Z

When I talk to my dad (who would be considered somewhere between a boomer and Gen X) about bands like The Sisters of Mercy, who would indisputably be called goth today (even if they don't identify themselves as such, haha), he argues that they aren't. I know goth in the 70s was originally called post-punk or new wave, which is what he calls it, but if that's the case, then what would someone his age think of as goth? I'm interested in how the meaning of the word has changed, and also would love to learn the history of the genre, including the things that once might have been called "goth", but now might not be labelled as such. I'm especially interested in perspectives from older goths, as, like I mentioned, I'm pretty young and only got into the scene around 6-8 months ago.

Thanks!! 🖤
