You can speak freely about these things, Just people who are “conscious” about politics will not approve of you. Wearing communist regalia is a rebellious statement in western society, And most of those people actually do not understand what they are trying to support. Usually see the Che shirts around people who think they are Rastafarian because they smoke weed, But have never actually been to Jamaica, And they listen to Bob Marley too much. The millennial and under generations I feel will move further away from this because the status quo is becoming modernism, And people respect the rich or “the right” more than radical liberalism. Kids born today will do nothing but work and their cultural experiences will take place on the internet.
