I dont' believe in a "god". why?
god is unknowable. some clergyman or the Pope, or an Imam or pundit, is telling you what some people long ago who wrote the Koran or Bible thought was right.
morals don't come from religion. and there is no contradiction in being non-theist and living in society as some Christians think. Things like "love one's fellow man" don't come from religion. Basic civility is something that exists in all human cultures, the Bible didn't tell us this. We have morals as a system of getting along, which is independent of any religion. Most morals of 2016 UK are independent of the Bible anyhow. Social equality, anti-racism, anti-sexism, are not inspired off the Bible. Sexual openness isn't either. If anything, Christians who espouse these values are not living per the Bible's teachings, they are the dishonest ones, not theists.
And it's not part of being a "minority" either. Most people of our age don't give a **** about religion, it's people who are blinded/dogmatic who project that society is religious. if anything, non-theists are the majority and secular thinking is the norm now, not blinded people who live in sheltered worlds.
