Should the devout Muslims/Jews/Christians unite against secularism and immorality?

They should certainly make a united stand against extremists who preach violence in the name of religion. However, people should certainly have the right to live their lives free from religion. As for immorality, it can be incredibly difficult to define. Is taking a young boy and circising him a morally acceptable act? I don't think it is, but a devout Jewish person would see no problem.
