The bare minimum Torah one has to uphold. “
Not that I tell any Yid what to do, but the fact is that what you call “the bare minimum” IS the halacha. Otherwise, one is NOT following the halacha as directed by Hashem. That is what some people tend to forget. Following additional strictures/Chumros to help people who might feel they are too weak to otherwise uphold the law and therefore cannot maintain the bare minimum, DOES work for those people. But those who follow that bare minimum are not reshaim, though they clearly are perceived as less observant Jews. They are also shomrei Torah u’mitvos, and we should not forget that.
