You continue to miss the point. Let's try again.The idea of not accepting those who would lead us into immorality is pretty plain to me. I am surprised it seems elusive to you.
Within the church we should not tolerate flagrant sin. Outside of the church we should not expect people to live Godly lifestyles. There's no point trying to force people to change from the outside inwards, we should be looking for people to accept Jesus and let the Holy Spirit change them from the inside outwards.
Simple example. I don't go round killing people. If the law were changed such that it were no longer illegal to kill people I still wouldn't do it, simply because I don't have the desire to do it in the first place.
What's so hard to understand about that?
Many more issues, and whichever way you vote you're taking chances with who will get into power. Although for all your apparent indignation at having the words "vote Republican" attributed to you when you didn't explicitly say it, this paragraph does pretty much imply "vote Republican". If you could never vote for baby killers or advocates of gay marriage you would logically have to vote Republican on the basis voting for anyone else pretty much hands the election to the Democrats. Unless you're trying to say that the Republicans are also baby killers and advocates of gay marriage, which isn't a position often attributed to them as far as I can tell.If having two bad choices on the ballot is what we are driven to, we still must decide based on what we have. In your example, choosing between baby-killers or enemy-killers, I think I can make that distinction. There are many more issues than those two, however, and all must be considered. I will never vote for baby-killers or gay-marriage advocates. After that, my choices require more thought.
