It really all boils down to this.... vape what you like, let others vape what they like. If someone posts a negative opinion to your favored device, that's their opinion. If you just ignored it, everyone would be happier (yourself included) in the long run.
Sent with one hand, the other is busy vaping.
Ironically, if people did follow the part in bold, there wouldn't be entire threads started with the clear intent to bash other people's choice in PV, and so there would be no need to ignore stupid threads.
