Not in the 21st century it isn't!
As an Anglican Christian myself I'm very open to other beliefs, be they Catholicism, Muslim, Atheism or whatever, and know myself that I am not perfect (ie. I drink a fish and curse like a fucking sailor and fantasise about the fairer sex like any other male), but I know that God did not make us all to be the same, otherwise life would be boring.
Personally I worship God in my own way - playing bass guitar in my church's music group and in my local Boys Brigade (and some of the BB officers and music group members are drinking buddies!). It feels like I'm giving something to the local community as well.
