Well, your condeming religion, in it’s entirety, because it has bad aspects to it. A lot of things humans do have both good and bad aspects to it.
The key is to try and emphasise the good, and discourage (or disallow) the bad.
In the case of religion, the “good” aspects to be rewarded or emphasised are charity, “goodwill toward all” (to me means no stealing, no murdering, even from/to strangers), having strength and hope for the future in rough times, giving others the strength to get through rough times, for example.
The bad ones to be discouraged: Using god to justify the pursuit of selfish goals and power, using your brand of faith to “judge” others as unworthy (which is a form of arrogance and ego building).
So you trust these moral codes because they come from “moral intuition”, but don’t like it when they come from the moral code of religion?
So, may I paraphrase thusly?
Well, what if your gut is wrong? What if your gut has no opinion?
How much of this “moral grammer” is intuition (which I see as hardwired, like instinct), and how much is learned from the society we grew up in?
In my opinion, intuition can be as flakey as any other aspect of humanity…
I never went to church. I do have a sense of right and wrong as taught to me by my parents. It seems wrong to me to dismiss folks for having a spiritual side to them as nutjobs, and religion as a whole, because of the imperfections that exsist in all of us.
I do believe (hope?) that we can all find a happy middleground somewhere.
