I do know a whole lot of people who fulfill this to the letter because they have horrific self esteem.
But setting this aside and returning to the point, I think it applies to everyone- at least, I try to behave that way. Regardless of what YITZCHOK2 may think of me from that other thread, I do try to respect and be kind to people across the gamut. I think it’s important not only to make a kiddush Hashem but also to just be a good person. I’m not sure I could be more specific than that- it’s just a feeling. Like you need to be a decent person.
I’m getting very bad at saying what I mean today, I think…
What the mitzvah in the Torah is, I don’t know. However, it would seem that even if it’s only regarding Jewish people, it wouldn’t be only regarding frum people. The Torah never really differentiates between frum and nonfrum Jewis regarding mitzvos, to the best of my knowledge, except in regard to apikorsim. This is all to the best of my knowledge- I’d love to find out if I’m wrong :).
