Posts like those from HaKatan sicken me.
I live in a Modern Orthodox community which also is home to a right-wing yeshiva and kollel. The yeshiva and the people in the community get along very well. There is a weekly chaburah, people have chavrusos with kollel guys, and there are Shabbos meal invitations sent both ways.
Contrast that with a community I used to live in which also had a yeshiva. The Rosh Yeshiva told the yeshiva guys that he didn’t trust the kashrus of the community Vaad (made up of the Rabbonim in the community) and they shouldn’t use it. He openly insulted the entire community and said everyone there is a tinok shenishba. Then he wondered why the community didn’t support his yeshiva.
I know which group HaKatan falls into.
