Talk politics.

Yep, this. Things like gender equality, anti-racisma and homophobia movements (not embedded in our culture yet, but it will be by the time I die), the rule of law, democracy, faith in the scientific method; these are the good aspects of our society we should be holding on to. The greed, the colonialism, the remnants of racism and homophobia; these are things we should work to jettison just like the Muslims should be jettisoning some of their less perfect attributes. I think multiculturalism has helped all of these things.
