Your post is reminiscent of a scene from CS Lewis's 'Out of the Silent Planet', where the protagonist is ordered to abuse a church crucifix.
It also made me ask, why?
I'm an atheist but I wouldn't want to gratuitously cause offence.
One of my friends has had a similar lifelong reaction from some people, about being a vegetarian - some folk just can't leave it alone and constantly go on about it.
Atheism, vegetarianism, train spotting - their all personal choices.Just let it lie.
