Teen Gothic

I circled the relevant text to make it easier to follow.

In the other argument they're having, they are trying to call out someone for being classist and hypocritical for saying its wrong to shop at shein??

For my interaction, i don't know what i should say, how often do you come across people like this and should i just ignore it from now on?

There is more i couldn't fit, they told me trad goths are snobs, i replied saying they're the base other fashion styles and expressions branched off and they continued to tell me trad goth is just a subset and i need to stop listening to 'old heads' (elders). After this i told her they're the ones who created it and i just gave up because they weren't listening to me.
