1) There's no evidence to support such harsh legislation, you want legislation against something you find personally annoying. That makes you something of a fascist. Well done!
2) The risk of long term damage from PG/VG is calculated by people who know the science properly to be massively smaller than the known effects of lit tobacco in any case.
If PG is so bad, why is it approved for use in hospital air systems for it's antibacterial values? Or why do they propose it's use it as a carrier for anti-rejection drugs for lung transplants?
Sounds like you're just making things up again, you know, unless you claim to know more than both Public Health England, and the Royal College of Physicians on this subject, which given your previous attempt at sciencing seems unlikely.
