That's why we have concepts like academic freedom and the freedom of speech, just because one groups beliefs are hegemonic doesn't mean they are right or true, hence controversy, debate and dialogue may lead to a better set of beliefs. Until someone then challenge's those beliefs and perhaps a new paradigm establishes itself. Sanctioning and silencing someone for their beliefs prevents or delays this from happening at worst and can lead to horrendous violence. Today's belief will one day be viewed as wrong-headed, superstitious or another example of group hysteria. A little humbleness on the part of everyone might lead to a better outcome. I'm no friend of any group that believes they know what is true, especially when it comes to human affairs. If you don't believe me, then read some of the books that Peterson suggests or speak to people who have lived in countries that have repressive or authoritarian regimes.
