yeah but if you are invited or otherwise to have a mature conflab about something that portends to be socially acceptable by even normal western social standards, discuss something prickly, to find that you have been tricked into a trap is going to get anyone's dander up.
The whole exercise was designed to anger and offend, with no mollifying offset. A true discussion would have presets and warnings, with an agenda that was clear to the participants.
Let me give you by way of explanation example:
When Independence Day the movie came out in 1996 I treated my wife and children (13 and 11) to share a viewing on father's day. I'm no prude, but one thing I wanted for my kids was a solid, traditional I guess, grounding in knowing their mum and dad believed in basic decency role modelling (thus shooting aliens and rooting for the USA as the good guys who save the world). So when the Bond's (under new ownership) add comes on with women sticking tongues down each other's throats and near naked men cavorting with each other and I'm trapped in row of chairs (just like the Muslim and his kid in that clip we are talking about) I was stupified and angry; as were many other adults as it turned out with the theatre admitting I was not the only irate father on the day and the Bonds Ad had been pulled as a consequence .....my wife boycotted Bonds from then on and I refuse to buy their stuff to this day.
Because the nearest things to the missing link writhe around semi naked in music videos clips and facebook is filled with schlock, base humour and depraved mischief doesn't make it right and because Islamists don't like the vulgarity and disrespect of the actions of the few doesn't mean I should take a binary view in place of an analogue of ideals. I should be afforded decency of knowing I would be offended before I am to be ridiculed via shock videos for my moral code, just like movies and television shows must show a rating that represents current (majority) social ratings.
