Please read my comment carefully, I did not do that. It is pretty obvious that the dynamics of how groups work and how you get people to believe in certain goals are pretty universal. Populism is designed to abuse how everyone perceives and judges outside information for political gain. Therefore it is viable for any political orientation. Other strategies are very significant as well (left&right). Populism can be found on the left and the right and should be criticized everywhere.

I honestly think you're just throwing around buzzwords, how is all of this this directly related to fascism? You're essentialy making fascism appear pretty harmless by using it as a catch-all phrase.

And if you can't be friendly to people with different opinions, your opinions are only a result of one-sided socialisation, not of discussion and reflection with the help of others. And therefore on the same level as any other unreflected opinion.
