I got you. I could make the argument that population control (through abortion) affects everyone around them. If we had the 59 million aborted babies since 1973 contributing to the economy, we might have a stronger SS program, as well as more people who had to buy into Obamacare. Their absence affected everyone around them.until it affects everyone around them then we have to look a bit closer. As in all things, not black and white there is lots of gray

It's a "what if" argument.....
I personally agree with our immunization program. I also agree that parents should be punished for putting others at risk. The issue of forcing people (against their will) to inject chemicals into their system, however, under the wrong regime -- can quickly unravel.
