The give away:
“Nearly 1,200 children from the U.S., Canada, Jordan, Turkey, South Africa and China participated. Most of the kids came from Christian, Muslim or non-religious households, with a small number from Jewish, Buddhist, Hindu and agnostic homes.”
How much you want to bet a large percentage of the sample were in fact Muslim...
I don’t trust this at all. Study after study shows that Republicans (a good portion of which are Christians) give more to charity than Dems (who happen to be largely atheists). And you know that the majority of “relgiois” people surveyed in Turkey and Jordan were Muslims.
In our sample, 23.9% of households identified as Christian (n = 280), 43% as Muslim (n = 510), 27.6% as not religious (n = 323), 2.5% as Jewish (n = 29), 1.6% as Buddhist (n = 18), 0.4% as Hindu (n = 5)

Also if you are a child in a religious household and that religion is being persecuted by secular authorities or authorities of other faiths wouldn’t you naturally develop a distrust towards outsiders?
Sounds like a good bet. Also a good way for the author to push a lie without actually lying (I'm sure most of the readers would have equated 'religious' with meaning 'Christian'), and the author would do nothing to deter that notion.
