Without invoking Godwin by hauling up Hitler, I liken what the liberals are doing to what social conservatives do who are of a certain mindset over abortion.
There have been numerous studies done, including one by the Baptist university, Baylor, that show no connection between abortion and breast cancer. Unwilling to let their fervently wished for connection go, these people actually pray for a cancerous connection to be found. In essence, they pray for cancer, not unlike liberals who pray for a lunatic-rightwing connection. He who loudly predicts evil in others is making a self-fulfilling prophecy.
