The generalization may be huge, but you wouldn't feel that there is a huge number of people who act like that?
There are people everywhere who are judgmental of other people's lifestyles.
When an LA girl who flipped out, comes back for Pesach with her husband in Kollel for 15 years, and her 9 kids (oldest 13) are wearing hand me downs, there are some in LA who will be judgmental, and some who won't.
Every society has some people who don't give slack. Lakewood is no better. Being that Rechnitz fits in in LA, no one is judgmental of him there.
The funniest thing is that his whole speech was judgmental of Lakewood.
May his many zechusim protect him, he committed a massive sin IMHO.
