Sechel…why do i so often begin my posts in response to Lubavitchers with the words “where do i begin.” There’s just layers and layers of… I’m not sure what it is. You can call it klipos.
First, even if it were common to see very untzius cleaning women and employees, that is still the “outside.” They are goytas. They’re not in the community. No frum jew would see them and have a minimized view of tznius. They might have shmiras aynayim issues, but that’s a separate issue.
The reality is that yeshivishe homes are, in fact, makpid that the help wears some sort of clothing, without giluy erva and the way they dress in the street. Most frum restaurants are the same. I’ve never seen a frum restaurant with women in states of undress.
So the presumption is wrong on two levels; factually, and in theory.
On to reality – having members of a Jewish community who are “frum” and are considered fully integrated without mitzvah observance weakens the mitzvos that they are not keeping in the eyes of those around them. That’s how lashon hora becomes acceptable. And that’s how boys end up falling away from learning, while girls gravitate away from tznius when their neighbors do not keep hilchos tznius.
This is why the frum community of crown heights has unique problems in this regard. Because they tolerate half baked BTs and gerim who don’t keep halacha, it has a trickle down effect on the mainstream.
One should not feel that they are frum if they abandon mitzvos, even one of them. You can show love to distant, sinful jews – whether they’re tinknos shenishbu or not – without bringing the mess into klal yisroel.
