Culture based Fascism

Can you control someone purely from culture? Its an interesting question as increasingly i feel that cultural attitudes are attempting to play a police like roles that our legal system/political system struggle to address.

Culture is hard to define, but to me it is a set of unwritten roles/norms/beliefs that are enforced by non-authoritarian power through social means , i.e peer bullying, segregation, shaming, economic hardship.

The major issue I feel is that the world is getting more mono-cultured as we go along, even though politically we are as divided as we have ever been. The two in fact appear to be moving in opposite directions...politically, the world is moving to the right, yet culturally, the viewpoint is strictly to the left. Worrying, the prevailing cultural standpoints appear increasingly to the only ones that matter, and there is becoming less room to question these standpoints without the non-authoritarian power being applied against you.

i.e In the workplace, if you question the effects of feminism, or homosexuality as solely positive, you can lose your economic livelihood as business exit you from the business. This has played out in quite a few cases; from Jamie Dormore at Google, to Israel Folau and Rugby Australia. Even though these opinions are commonly held and don't affect the quality of work in their careers.

Surely you should be able to question and hold different beliefs than the prevailing culture and not receive a penalty.

So the question is what to do about it. I'm not quite sure.
