I've been dealing with anti-gun and anti-2nd Amendment folks for years. That experience has given me the ability to deal with the anti e-cig crowd in the best possible way for me.
I give them a dirty look, and dismiss them.
If they're going to spew ignorance and refuse to look at the data and personal experience of others, then why waste my time and energy in trying to educate them. Don't get me wrong...I've helped convert 3 folks this weekend at the parental festivities leading up to my daughter's prom, but those that are snooty about the topic without willing to consider the other side are a waste of time. Those are the same people that probably believe the earth is flat and air travel is fantasy.
As for the 3 I converted this weekend, all three are smokers that saw me with my MVP v2.0, and wanted to know about it. I loaned them each one of my eGos with a new CE5 loaded with 18mg nic Midnight Express from NicQuid, which is close to the acrid taste and flavor of a real cig...at least it is to me. I've heard back from two of the three, and they will be getting my equipment back tonight, after they pick up their own set-ups. The third one is still on the fence, and will be coming by tomorrow to try a few of the other flavors that my wife and I enjoy. If 2 of the 3 convert for good, I'll be happy.
