I'll also add that the government already forces us to pay for things like the Iraq war or exorbitant spending on the military which many people oppose morally. Do they get to pay less taxes?
Having a military and law enforcement is the entire point of having a government. It's exrtraordinarily difficult to enact what you have just specified because a war has a similar result on all citizens. It's not something an individual can opt of of having. I cannot live in a US that did not invade Iraq while my brother lives in a US that did. It's not something that can be individualized. Birth control is. You can decide to acquire contraceptives and I can choose not to. They are made for individual consumption.
And those things lead to many lives being lost (in the millions due to the Iraq war), yet do pro-life care about that?
Most do (Or are you asking me in particular?), but that's sort of unrelated to having free birth control, isn't it? The government mandating contraception coverage isn't going to undo the Iraq War.
Or do they only care about making sure people don't have sex unless they want to have a child. Pro life people should be in favor of contraception since it will stop later abortions from occurring.
Not at all. I'd gladly accept this stupid mandate in return for outlawing abortion but that's not on the table and will never be on the table. That's like asking if I'd rather have someone commit murder or masturbate. I'd rather they do neither. I want the murder to be illegal and I want the government to make it difficult to do. It doesn't make any sense for the government to outlaw masturbation for obvious reasons, but I still don't want it subsidized.
Now of course, you'll argue that subsidized access to contraceptives reduce the number of abortions, which my previous analogy doesn't follow very well, and while I'm not sure we have statistics to back that up (Most people would ask for them if I attempted to argue that parental notification laws reduced the number of abortions) but we'll assume that they do since that would make logical sense.
That's essentially saying the government needs to pay people not to commit murder. That's backwards. We shouldn't reward people just for not murdering someone, but rather punish those who do.
But it's not about the life is it, it's about religion......
This discussion mostly is about religion. We can have another about abortion sometime if you would like, but that's a little different than birth control (unless we're getting into the fight about when life begins vs. when pregnancy begins aka fertilization vs. implantation).
