I think that's a separate issue. As a general social rule you aren't supposed to bring up religion or politics at a general social gathering since people have strong opinions driven by their group affiliations. It hijacks conversations, starts fights, and doesn't accomplish anything since people will be arguing from an emotional reaction. That doesn't mean you can't ever discuss politics and religion, just be understanding if other people aren't interested in your views.
