The fighting amongst the layman is not what HKB’H wants certainly. Such fighting unfortunately occurs amongst any large group of people, Jew or gentile, Chareidi or left-wing whatever. Its not limited to any specific demographic group. Anyone who tried to convince someone else otherwise, is not seeking the truth but rather most likely on a hate-prone agenda.
As far as fights amongst Talmidei Chachomim, they are usually lsheim shmayim and each one truly believes they are doing what best for the Klal and what the Torah wants.
