Sometimes I just wonder to myself if Ha-Shem Yisborach is not kivyachol shaking His head from side to side, saying, “You foolish people – That’s NOT what I meant!!!!!”
Too often, people accept chumros upon themselves (as is their right) and start to believe that those chumros are halacha l’maiseh. Then when they see other frum people who have a different (not better or worse) hashkafa and derech, they look down on them as not being frum enough. It’s true, kol hamosif goreah (and isn’t it interesting that the Torah itself admonishes us not to add or subtract from the Torah). If all one can say about what they believe to be halacha is that they don’t know the makor, but they are SURE there is one, there is a problem. That is how some people go off the derech.
