Since you mentioned risk as a motivating factor, I hope you also decide to home-school your children, never have them in a moving automobile, never let them play any sport or climb a tree. Also, I have to assume you would never drink coffee, soda, alcohol or eat at a fast food restaurant in their presence.
This is reductionist and flatly ignoring much of what I said. I outright stated that everything comes with a risk. You have to weigh risk vs. benefit and make decisions accordingly.
Do I put my children in a car/truck and drive them somewhere?
Risk: Tiny risk of an auto accident.
Benefit: We have to go places, buy groceries, go to doctor appointments, and play at the park
[For me, the benefit clearly outweighs the risk]
Do I send my children to public school?
Risk: They'll be bullied or some maniac will shoot up the school.
Benefit: A proper, rounded (in theory) education, the acquisition of social skills, and the ability to make lifelong friendships.
[For me, the benefit outweighs the risk]
Do I expose my children to my vapor?
Risk: Very small, but nonzero, risk of toxic substances harming them, either in the short term or long.
Benefit: I don't have to delay my own gratification, or inconvenience myself by walking out of the room.
[Benefit of vaping around them is almost nonexistant and entirely selfish, and therefore not worth the risk]
You see how these choices are not all the same. They're not parallel. We're all forced to expose our children to risks. My position is that we're not forced to exposing them to NEEDLESS risks, and that's exactly what this is. The degree of risk is unknown. Most of us here think it's small. If we DIDN'T think it was small, we wouldn't be vaping at all. But "small" is not zero. No matter how much one tries to rationalize or justify, it simply is not zero. There is too much unknown. So my point is this: Why expose them to the risk when the only benefit of doing so is that you're not inconvenienced?
