Turn their own weapon against them!
Today many of the evangelical Republicans base their opposition of progressives on a misunderstanding of many Bible passages (among other things!). I think that one of the only ways to fight against will-full ignorance on their part is to show them some Bible, rightly presented. Use it on signs or in personal conversations.
If you hate the Bible in its entirety then this tactic is not for you. Please don't piss on it for those of us who feel it can produce results. Thanks!
Here is a winner from the Old Testament (where many evangelicals live):
Proverbs 6:16-19 (New Living Translation)
16 There are six things the LORD hates
no, seven things he detests:
17 haughty eyes,
a lying tongue,
hands that kill the innocent,
18 a heart that plots evil,
feet that race to do wrong,
19 a false witness who pours out lies,
a person who sows discord in a family.
Who could these describe? Hmmmmmmm...... I also think it might be the Republican Platform!
