Would people think it was disrespectful if I dressed my kids as the devil and went to the Mosque? Would it be ok if I wore a bikini to a Mosque (as another poster said). Or took my kid to a Synagogue dressed as a ham sandwich?
Are no faiths allowed to be offered consideration by people using their places of worship?
I think that if there was a centuries old date in the calender that was culturally accepted and celebrated as Dress Like a Devil Day and the mosque held an open play group on the morning of Dress Like a Devil Day, without specifying what your religious persuasion has to be in order to attend, and a couple of small children came wearing devil horns, they would be misguided to choose to be offended.
Same goes for Dress in a Bikini Day , where most of the country dress in a bikini, and the Mosque decides to hold an open day on that well known day, and gets upset that someone turned up in a bikini on their way to Sainsburys.
Or the old classic, Dress Like a Ham Sandwich Day, on which the synagogue decided to host a community get together, and a couple of kids came like a loaf of Kingsmill 50/50.
When you throw open the doors of your place of worship to the wider community and welcome people who do not hold your religious beliefs, you absolutely must be prepared to deal with the fact that what comes through the door won't necessarily be the same as you, and might be challenging. Not everyone knows the rules.
Now would be a good time to excercise the Christian belifes of acceptance and compassion, tolerance and peace to those little pumpkins and crack open the Chupa Chups.
