‘religion gives you permission to perform these discourtesies’

I am nearly always inspired by Richard Holloway. I was struck by a particular recollection of his, found in this BBC Hardtalk interview at 4 minutes 22 seconds. He speaks of the shame he felt at having sent his hard-working labourer father a ‘pious’ letter urging him to embrace Jesus, RH remarks (with tears in his eyes) ‘religion gives you permission to perform these discourtesies’.  Indeed it can.  The whole interview is worth watching.
