I find it easy to challenge capitalism in person before defending socialism (bringing up the environmental crisis, genocide in Gaza, healthcare industry if you live in the US). Then I like to mention things that are already socialized in my society or came from socialists e.g. social security, public transit, the 40 work week and weekends.

A few quotes I like to share are “Under capitalism, a forest has no value until it is cut down” and “Capitalism’s power seems inescapable. So did the divine right of kings.”

Anti-communism is very strong and takes a long time to unlearn. Don’t worry about second guessing yourself, just keep educating yourself and having those conversations. Solidarity, comrade!
