I sometimes see a teen wearing a Ramones or Zeppelin t-shirt and smile, assuming they know and are into the music. Even if they don't and are wearing it for some obscure reason, i say let 'em! I would never do it, however, that is, back in the day when i wore rock t-shirts.
Reminds me of people who wear shirts picturing places they have never visited. I did that myself once, when someone gave me a t-shirt from their vacation. I liked the color and fit of the shirt and it suited me well when taking a strenuous hike. Fortunately, no one questioned if i'd been to Portland, OR, or threatened to rip the shirt off my back.
