Yes, there is much that secular Jews can do to improve the situation, but that is out of our hands. We can only change ourselves, and hope that is a step in the right direction. As Pirkei Avot says, we are not incumbent to finish the task, but we are not free to stop. We cannot punish our left hand by injuring it. Such an action is insane. We must care for each Jew with the love and care we show to those most beloved to us, for they are beloved in the eyes of Heaven.
To those who try to build Judaism by destroying it, I can only hope they are judged mercifully by the Heavenly court. In the court of public opinion, they have already been found guilty, and have done untold damage to the mantle of Torah.
For the sake of Heaven…many have gone in the other direction.
