I here your church complaining about abortions, not gun accidents and the others you listed. Thus, this list is irrelevant to my point.<quoted text>
Churches teach abstinence until marriage. This is the number one, absolute, 100% method to prevent an abortion.
It is not their place to teach how to use contraceptives any more than it is their place to teach sexual positions.
It isn't their place to teach gun safety tips to avoid accidental deaths.
It isn't their job to teach drivers education to prevent car accidents.
It isn't their job to teach chemical reactions to avoid accidental science fair mishaps at home.
It isn't their job to teach how to paint to prevent accidental falling off ladders.
I hope you get the point.
You cannot expect me to take you seriously if you think Church holds the responsibility to teach these things. They teach the gospel of Jesus Christ (at least mine does, the one you are currently attacking)
How is fighting gay marriage a job of the church? This is relevant.
