Another interesting point is that tznius is “controversial” for the same reason Kollel is controversial. People don’t want to hear about it. They feel inexplicably threatened by those who maintain tznius and those who learn in Kollel. They feel inherently inferior to those who maintain traditions in the proper manner, so they must lash out at those that do, to attempt to bring them down to their level.
The proper attitude is of course to raise their own levels of kedusha to a higher madreiga. And if they can’t learn in Kollel, certainly a reasonable possibility, at least support (rhetorically and financially) those that do.
