Because YOUR values discredit/dismisses everyone else's values.I think these are two ways of stating the same thing. So the "pros" list stands at one...the reduction of anxiety about death/meaningless life.
I hear this one all the time and I hate it. People say religion "fosters community" or other things that are similar to what you said here about group solidarity. However what this fails to take into account is that and "group solidarity" caused by religion is really exclusionary when we look at the wider scope of our global community.
I use the sarcastic example of a community Block Party. Which is more inclusive:
A. Fourth of July Block Party!
B. Fourth of July Christian Block Party...Jew Free since 1985!
I argue that perceived group solidary via religion is actually a negative force that promotes xenophobia and excludes members of other religions or of no religion from the supposed cohesion. In 1987 when George HW Bush said that atheists should be considered neither patriots or citizens of the United States, I'll bet Christians everywhere felt cohesion. Not so much for the rest of us.
Striking this from the list, the "pro" column still stand at one entry.
Non-religious give just as much to charity as religious people. What's worse is groups with religious names take credit for non-religious donations. For example I give very heavily to St. Jude's Children's Hospital. That is counted as a Christian charity even though thousands of my atheist dollars go there every year. Increasingly there are non-religious organizations like Chive Charities. This one is a wash, and for that reason I'm striking it from the "pros" list and we still stand at one positive effect of religion!
I got married by a Justice of the Peace, no religion involved. Most life milestones are not religious...graduation, buying a home, bearing children. Strike this from the record!
The list still stands at 1.
As I, and several others have pointed out, some things can appear as both positives and negatives, operating in different ways. And the way we choose to apply our values decides how much each item belongs in each list. You've clearly decided that anything that anyone wants to credit to religion, you'll just negate and move along as if they said nothing.
