The "doucehbag stigma" comes from multiple sources.
First off, the Media (being the wholly-owned subsidiary of and total ..... to the same Globalist Financiers who own most of Big Pharma) has mounted an aggressive anti-vaping campaign because vaping is cutting HARD into the profit margins of their dealth-dealing puppet masters. Since they have no actual SCIENCE or FACTS to use to discredit ecigs, they resort to ad-hominem attacks, and attack the PEOPLE who are vaping, by demonizing them and portraying them as snooty or obnoxious.
Secondly, it is a simple statistical fact that because most vapers come from a general cross-section of the general population of smokers, that there will unavoidably be people who actually ARE douchebags that are becoming vapers. It's simple statistics...
And thirdly, it is a matter of the social conditioning that our culture has undergone over the last several decades. This planned agenda of social conditioning has led the general public to perceive anyone who takes the initiative, takes PERSONAL RESPONSIBILITY for their own life and health, is motivated to be successful on their own outside the system, and ESPECIALLY anyone who expresses distrust or disdain for the Government and Corporate Powers as being rude, obnoxious, intolerant, and even dangerous and a "threat to the Republic".
In other words, yes, vapers are perceived as douchebags because some of them ARE douchebags. But MOSTLY it's because the public has been programmed to see anyone who is happy, healthy, and independent as a threat.
