DaMoshe,
He once told me that there are times he regrets becoming frum again, just because he hears from so many people how being Modern Orthodox is against halachah, how being a Zionist is apikorsis, etc. He said, “If I’m doing wrong anyway, if I’m an apikores anyway, why should I bother trying?
In this world, there is nothing that anyone can do that someone else won’t disagree with. If a person has explored the options and made a choice, why favor the opinions of those who disagree with that choice instead of associating with those who would make the same choice? There are billions of Christians and Muslims who think we are all wrong about our religion; many of them believe we are going to burn in the afterlife because of it. Should I abandon Judaism because they say this to me?
If you are MO, Hareidim will disagree with you. If you are Hareidi, MO will disagree with you. If you became Chabad, Satmar would disagree with you. If you became Satmar, Breslov would disagree with you. I have heard religious Zionists insinuate that Jews who do not say hallel on Yom Yerushalayim may potentially face consequences after 120 because they did not appreciate Hashem’s miracles performed for them. I have heard others state that Jews not living in eretz Yisroel will have a diminished status when Moshiach comes and may not be allowed into the land at all because they didn’t appreciate it. Should non-Zionist Hareidim stop being frum because this was said about them?
My point is, serve Hashem with all of your heart, all of your soul, and all of your strength. That’s the best any human can hope to do, and Hashem is far more gracious and compassionate than humans.
