“meno: For EVERY jew that was not religious and wouldn’t have become (which was a lot) it was the BEST thing that could have ever happened to them!”
What? I would never differentiate between religious and non-religious Jews in a matter like this. For one thing, we don’t know who really is religious and who is not. There are many Mitzvos in the Torah and everyone has a different bechira level and we have no idea who is on a higher level than who. There can be people who are considered “non-religious” who are actually on a much higher level than some who are called “religious”.
We do believe that Hashem controls everything in the world and that Hashem loves all us, religious or not, and therefore whatever He does to us is in our best interest. This applies to both religious and non-religious Jews.
However, as I pointed out, I would be careful about the context in which I apply this concept. Of course, technically, it applies everywhere. But when you are talking about something like the holocaust, it is a concept that can’t be explained in one sentence, and therefore it is better not to say such things in a forum in which it would be impossible to explain what it means. Since it can easily lead to misconceptions.
