Souls are judged with no consideration of their worldly influence and prosperity; the only criterion relevant to the evaluation is justice.
One may be able to defend himself in a trial before a jury. But if one lives in admiration and pursuit of injustice, will be unable to defend himself before the jury in Hell: he will be condemned in the most important trial of all.
So what I see is that people that support unjust causes are liable to be be guilty in the most important trial of their lives. I see people support Left Wing causes that advocate taking money from people that earned and worked for it and give it to people that did not earn nor work for it. And they do not seem to be worried that by supporting stealing they are liable to arrive in the next world with guilt in their souls. I see people that are afraid of leavened bread on Passover but not afraid of lying or defrauding their neighbor.[one should be careful not to eat leavened bread or cake on Passover. But the degree people take this is beyond the Torah.]
I claim people should be more afraid of pursuing injustice more than anything else in the world.
And I see many religious people that are concerned about the next world but do not seem to think pursuit of unjust causes has anything to do with it. They apparently think all kinds of mantras or other extraneous things will help them. Thus, religion can become a cause of injustice by distracting attention from what really matters.
Pursuit of social justice is always pursuit of injustice. Always. It is always taking from people what they have earned and worked for to give it to someone who has not.
Pursuit of building any religious movement is always pursuit of injustice.
