Every very last perpetrator of evil must be discredited and banished. The problem is that you cannot fight them on their terms and win using the very instruments of evil that they employ to sustain their vile agenda. Also, realize that the worst of the worst are still your brothers and sisters. Living with them will go on even after the adversity has passed. The wisest thing is to stick to your principles and be the example that they need in order to redeem themselves. It is an arduous, lengthy process that will meet with vigorous opposition. Just be prepared to weather the storm.
