Themes and Underlying issues in 'Jesus Revolution' and our own times

How can we utilize the watching of this film 'Jesus Revolution' to develop the discussion of the relevant themes and issues between the 1960s Jesus People who the traditional church struggled to accept with the issues of our own day?
Many of the hippies of Southern California in the 1960s were
becoming followers of Jesus. But the traditional churches did not accept them and there was a lot difficulty experienced by all people involved. Songwriters like Keith Green and Don Francisco came out of the Jesus Movement and many contemporary worship songs were influenced by these songwriters.

There are several relevant factors that can be applied with the film and our own times in 2023. What are they? How can we develop this into creating something for marginalised subcultures in our own day?
