I mean I’ve studied it before and practices of Judaism, so I understand what they do and what they (are supposed to) follow.
There’s clearly a problem when someone wears a nirvana shirt and owns a bunch of records, and knows the singers, but they don’t even listen to a band or only heard one or two of their songs.
And then there’s me, who doesn’t care about nirvana. I pretty much don’t know anything about the band but probably heard one or two songs.
