Religion doesn't do a single thing.
People do.
So, to say that Christianity isn't concerned with this or is concerned with this or prone to do this or that is inaccurate and makes one prone to several errors in thinking.
To paraphrase Charlton Heston, "Religion ... it's people!!! It's made out of PEOPLE!!!"
We've all had good and bad experiences with people and religion. To me it's all about the tendencies of people and not something outside of people acting upon them. To think eradicating religion will eradicate certain types of problems is using a scapegoat (and interestingly ironic).
