Oh I agree that parents are not always welcome, I'd be shocked if they were. I just want people (esp. Christians) to care enough to take a stand. My motto is do the minimum! People shouldn't try to(or expect to) change the world. Rather they should try to find what specific thing (minimum) God want's them to do. And then do it faithfully. For most it will be voting, praying, and maybe giving money(to support lawsuits.) The minimum is different for different people. For a few it will mean getting involved with politics, or becoming a teacher, etc.
I don't expect us to win every battle, or solve all the problems. But there are so many problems that could be fixed, if people tried. Take abortion for example. Only half of Christian voters bother to vote, and a large number of them don't vote pro-life. If most Christians would vote pro-life regularly. At the very least we would have more pro-life senators. Could you imagine the impact that a few extra pro-life votes would have over time. For example what if we had the votes to put Bork on the Surpreme Court instead of Kennedy? etc.
