In characterizing this trend, it seems as though you are assuming that membership in these various communities is mutually exclusive. However, this doesn't have to be the case. For example, a person may be both a Catholic and a leftist. Thus, a good follow-up question might be: To what extent does leftist politics and Catholicism have an impact on a person's evaluation of risk. For example, one could compare Pope Benedict with Pope Francis, who are both Catholic, with each other and potentially conclude that income inequality/exploitation influences Francis' conceptualization of risk to society to a greater degree than abortion or sexual immorality.
