Funny you should mention that. Because I'm a heavily tattooed person, and I was one long before it was common to see anyone, much less a woman, walking around with a bunch of visible tattoos. And I've noticed a similar sort of attitude within the tattooing community RE: younger people and how they are getting into tattoos. Instead of being glad that tattoos are starting to become "normal" and an accepted part of our culture, lots of people my age and older who were getting tattooed before it was "mainstream" act like younger people being into the stuff that we are into are somehow hurting us, or hurting the tattoo culture, or just somehow don't have the right to do what they want because they weren't there when it was a fringe thing that you had to sort of suffer for.
It's weird to see the same kind of attitude in the vaping community, using similar arguments and similar rhetoric. And really, to me it all sounds so much like "get off my lawn."
