That's a strange argument. It's not the non-vapers in the coffee shop who are objecting in the first place - it's the corporate talking heads and the local and state governmental entities. We're talking about law and/or policy here, not etiquette.
I agree and disagree with you. It starts with corporate, but through them, and the misinformation from the FDA (and other extremist non-smoking sources), it does enter the mind of everyday Joe Shmoe, forming his opinion. Thus, the uninformed, or misinformed public make demands for "protection" from unproven "dangers".
You don't have a very good grasp on the mechanics involved in public policy decision-making. It's not the pompous jerk sitting next to you who's causing the pv bans at this point in time - but it will be soon if we don't object vigorously now. There is no firm "public opinion" about ecigs yet because the vast majority of the general public has no idea what they are. And if you really believe that consumables in our society are made illegal for safety reasons, you really do need to rethink that. We have no shortage of very dangerous pharmaceuticals, over-the-counter drugs, and foods that are widely available to the public in every 24-hour supermarket and drugstore in the land.
Springfield Missouri has an 'ecig/PV' ban in effect, from a public vote on the issue. It is very possible that many voters had no idea that PVs were included in the no-smoking ban, that they had no idea what a PV was, or that they only received misinformation concerning PVs. Regardless, it was the people that voted.
PVs hurt the Pharmaceutical Companies! There is NO doubt about that. They also hurt the tobacco companies, not to mention the various Governments (County, City, State, Federal) by loss of taxes. THAT is the biggest problem the vaping industry faces.
As a disabled Veteran, I can attest to the dangerous drugs offered by the Pharmaceutical Companies, when there are natural ingredients that can do the same job, without the dangerous side effects, but are made illegal (in their natural form). As long as it is made synthetically, with other added chemicals by a Pharmaceutical Company, then it's legal. Pharmaceutical Companies have well paid Lobbyists, and can afford to romance Politicians.
As for dangerous foods..... we have an ever growing number of people deathly allergic to peanuts. Peanuts are a serious public health concern, but there are no City or State wide bans on peanuts.
I stated before, and I will state it again, I have yet to hear one Vaper state they blow plumes of vapor in the faces of others. From what I've been reading, Vapers are very considerate of non-vapers, not wanting to cause negativity about out habit, but they, and I, do not want to be reduced to being lumped in with smokers.
