“But the Chofetz Chaim is only followed when it fits with our lifestyle!”
I know you meant that to be condescending, but it’s actually a pretty non-controversial statement. There are all sorts of cases where Chabad doesn’t follow the Shulchan Aruch HaRav to the letter; I’ve had some pretty good, informative conversations with Sechel on here about why that is.
Have you ever met anyone who follows one sefer of collected halachah for all minhagim? Have you ever heard anyone say, “my mother’s mesora was Minhag Kitzur, but my father came from a minhag Be’er Heiteiv family?” It’s also not controversial to observe that we posken a lot of issues different in America than we did before (psst, Chabad also did this). What’s the big deal? Also, you surely realize the electric razor didn’t exist back then, right?
