Taking Christianity specifically as that's the only religion I know at least a little. Religions teach us to value love and compassion. That's nice, but not terribly interesting. They're not values that you couldn't arrive at through other means.

I don't see how those high-level values help in solving modern crises of global scale. Believers searching for specific advise on modern day problems need to work hard and read though a lot of "code" to find a few nuggets - ultimately failing to get satisfying specific answers.

If I do a web search on what the bible says to homosexuality, for instance, I get walls of text discussing precious few bible verses. In my view what religion does here is allow those in charge to enforce their individual preferences and opinions on their believers by means of laying out suitable interpretations of the code. This does more harm than good.
