I find very often that those who make the biggest issues on blogs about chumros are the kulah shoppers.”
Jose, I make a big issue about it, and I am most definitely NOT a kulah shopper, so you are mistaken in that. I am personlly machmir on many things, but that neither makes me a better Yid, nor a more observant one. If our Gedolim decreed certain chumros as halacha, then they ahve the authority to do so. But you know what, the Gedolim once upon a time wanted to include potatoes as kitniyos for ashkenazim. Do you know what such a chumrah would have done to klal Yisroel? Was it kulah shopping when they ultimately decided that would be a VERY bad decision? No it wasn’t, because the halacha is that potatoes are not kitniyos l’chatchilah. The l’chatchilah is the inyan. And if something is said to be mutar b’dieved, that might be a kulah, but the action could not have been strictly assur. More like a “better not to” type of thing.
