The tznius issue isn’t about anger, it’s about dismantling chabad supremacism. Chabad aren’t better than other groups, and have their share of communal problems.
I think it’s obvious that when you mix a large amount of baalei teshuva and gerim in s community, and stop everyone from learning full time at age 21, you’re going to automatically have kedushah problems. They’re lacking the safeguards of other chasidishe groups who send most to work at 19(however some do stay in kolel, and chabad has yet to see the importance this has in maintaining a community)
