Most people are born into a certain religion and then simply follow it their whole life; by follow, I mean they pick and choose to follow things based on time and convenience. They ignore certain things also based on time and convenience. So these are watered down followers - most people probably belong in this group I think. Maybe I'm wrong. This is probably true of all the major religions out there.
You mention morality and say that one should do good. Unfortunately, morality is relative to the time and geographic area; it changes from culture to culture and from one generation to another. 100 years ago, being gay was immoral but today, in many parts of our society, being anti-gay is immoral.
Following in the lead of people like Fred Rogers and Christopher Hitchens again leads us to similar conditions of a religion in some ways, at least. We only know them on the superficial levels anyway (not that it really matters much).
It's a tricky subject.
I guess most people nowadays seem to follow science, materialism, their pleasures, etc. The "live free" lifestyle is taking over the world. Sure, they may go to church or temple once or twice a week but it's all superficial.
Society is just as corrupt as ever whether people go to church or not.
Morality is not subjective. To demonstrate, if I were to be next to your infant daughter, and decided to rape her, how could that possibly be the morally white course of action?
It isn't, it's a morally black act; the infant was physically, emotionally and sexually harmed, in the name of sheer sexual pleasure.
As another example, in what way could the 40-day long rape, torture of Junko Furuta, and her death by her captors using more flame than intended, have her captors be morally white, and the victim morally black?
What people "believe" is acceptable, right, and wrong, definitely varies. But that does not mean morality is subjective. That hinges upon the idea that everybody is moral and strives to do moral things, which is childish naivety that borders upon insanity.
Take homosexuality. Who does it harm? Nobody, in and of itself. Who does homophobia harm? The homosexuals.
When two men love each other, and have sex with each other, who does it harm? Nobody. If a town gathers together to flay and murder those two men, who does it harm? The two men.
The former is neither moral nor immoral, it's not an issue of morality; nobody was harmed, and no harm was averted. It doesn't fall within the moral landscape. The latter, however? Two men were killed because they loved each other. That squarely places the murderers as immoral.
Bit long, but it's not exactly a small subject.
The difference between following in the footsteps of Rogers and Hitchens, and following religion, is that religion says you must do X and Y. End of, no changes. Otherwise it's not religion; it's opinion, it's not absolute. There is also the fact that Rogers was as peaceful and well-meaning a guy could ever hope to be, and Hitchens sought the truth and didn't shy away from bringing evil to light.
Whilst society wouldn't take too big a turn once it shakes off religion, at least in the near future, having people actually treat this one life we have with all the seriousness it deserves, and not believing that you can annul the most heinous of acts by praising Jesus, would do society a large amount of good in the long run.
