G-d isn’t letting you help these people. Read the Torah and you’ll see that if you have the desire and Hashem has a desire then there will be an explosive reaction and you’ll be able to save someone. What I do is focus on what I can do. I’ve had people close to me suggest that I do this or that. I do this or that and it doesn’t work. I then do something else and although it’s not the fireworks type of life that we hoped we’d be participating in we see that there’s a richness in the things that Hashem allows us to do. Doing anything for anyone else (like holding a door open etc.)is a tremendous opportunity.
And in terms of being the children of Holocaust Survivors my father told me not to hate people who were not directly involved. Most people are interested in fitting in and also we all have DNA and so if we don’t have a Torah education we don’t understand that Hashem finds it undesirable for the Jew and Non-Jew to marry. Assimilation is a very logical result when one doesn’t know how important it is to live as a Jew.
We are very priviledged to know that it is important to be religious and we should focus on whatever is within our power to please Hashem.
