I have no issue with people who adopt chumros. I respect them, IF they recognize that their chumros are NOT the Halacha, and do not hold themselves as superior simply based on the fact that THEY hold by chumros. Unfortunately, some who are very machmir tend to view themselves as better Jews, based on how many chumros they follow. And that, IMO is why so many people have negative feelings when they see so-called “frummer” people.
I don’t care if you want to only wear black with no color whatsoever (even the “permissible” ones). I DO care, however, if you look down on ME because I AM wearing colors. I care if you think you are more frum than my son because he likes to wear colored shirts and socks (anyone see the Shadchan letter in the Flatbush Jewish Journal last week, and the responses to that column? No, it was not my son, but the girl’s mother’s attitude AND the Shadchan’s made me very upset).
I said it before and I will say it again. NO one should mock anyone, but especially not anyone who is a Shomer Torah U’Mitzvos, even if that person does not subscribe to your personal Hashkafa. It is arrogant, it is sinas chinam, and most certainly is not “frum” behavior.
