Conservatives are using the wrong tactic. They should applaud when liberals have abortions. Had the Liberal's children grown up to vote and followed in their parent's footsteps, Gore would be president today.
Learn to use their own arguments against them and they might wake up. Well, no. they aren't that smart but it's fun to tweak their noses.
A clever idea. However if such statements were made, conservatives would then be accused of racism. I once had a conversation about abortion with a liberal. He was reciting the tired old mantra of Bush denying blacks the right to vote in FL in 2000. I countered that if blacks and other minorities didn't have so many abortions, Gore would have easily won the White House in 2000. The liberal then called me a bigot and ended the conversation.
