When does a human being become a person and why?
Again with this "human being" nonsense. If you want to ask how a "human being" is different from a "person", then you first need to clarify how a "human being" is different from "a human".
Or, if you were just being careless with your words and you meant to ask "When does a human become a person?", I would answer with "when it becomes sentient". This is not very scientifically definable, though, so from a legal perspective, I would argue "when activity can be detected in the cerebral cortex", as that's the earliest point at which anything that might be considered "thought" is possible.
Do fetuses have the right to own guns?
Just as much as turtles have the right to fly.
Seriously though, SCHIP provides free health care for children, but pregnant women do not get free health care, which can bankrupt a family just as they get started and occasionally sub-standard care puts lives of fetuses at risk. So are all the conservatives on this forum hypocrites, or will someone here defend free health care for pregnant women?
A false choice. I don't advocate taxpayer-sponsored health care for
anyone.
So you are against POOR CHILDREN having HEALTH INSURANCE.
NO. We are against poor children depending on a government system that takes ten dollars from us for every one dollar that it gives back to them. We'd rather just give them the money ourselves and tell the government to go fuck itself.
But, I assume by your inability to answer why you're willing to extend rights for non-born fetuses on the basis of humanity and not blah blah blah
WRONG.
Recognition for the rights of the unborn is based on two things: their inherent humanity or personhood or whatever, and the fact that they
haven't broken the law.
If a fetus somehow manages to escape from its womb, murder someone, and then climb back in there, then by all means, hold a trial and kill the little cretin. But I don't see that happening anytime soon.
