Teen Gothic

I hope this is the right place to ask. I'm just a curious metalhead who's not super familiar with goth culture (though I've always thought y'all are cool), so I apologize if this is a dumb question. But I have to know.

I see many goths wearing rosaries and I've always thought it's just because it looks good, but I came across someone saying that many goths wear it to express anti-conservatism or anti-christianity. I've never heard about that before and rosaries are a religious thing, so it feels counter intuitive. So I come to you to ask, is any of this true? Can someone explain the connection to anti-conservatism and anti-religiousness?
