Oh boy, if were to really go down this route of pandering to the "Offended Class" we would not even be able to open our mouths to burp, actually that does offend many people, although an old Uncle of mine who suffered with the wind, (a family trait, proudly continued by me and my offspring), used to belch loudly and then say:
"It's manners in Arabia".
So, you poor little wimp, you are offended by Evolution, Haloween, or Birthdays, are you ? TOUGH ! Grow up, nobody dies because they get offended, just go home and get over it, we in the real world will carry on as we bloody well like, and bloody well like the way we carry on !
