Well, apparently the same folks who must never, ever be offended have no trouble whatsoever offending other religions.
From this source:
It reads: 'On the first day of Christmas my true love gave to me an STD (sexually transmitted disease).
'On the second day debt, on the third rape, the fourth teenage pregnancies and then there was abortion.'
According to the posters, Christmas is also to responsible for paganism, domestic violence, homelessness, vandalism, alcohol and drugs.
Another offence of Christmas, it proclaims, is 'claiming God has a son'.
The bottom of the poster declares: 'In Islam we are protected from all of these evils. We have marriage, family, honour, dignity, security, rights for man, woman and child.'
The campaign's organiser is 27-year-old Abu Rumaysah, who once called for Sharia Law in Britain at a press conference held by hate preacher leader Anjem Choudary, the leader of militant group Islam4UK.
Former Home Secretary Alan Johnson banned Islam4UK group earlier this year, making it a criminal offence to be a member, after it threatened to protest at Wootton Bassett, the town where Britain honours its war dead.
Mr Rumaysah told the Mail that he was unconcerned about offending Christians.
He said: 'Christmas is a lie and as Muslims it is our duty to attack it.
'But our main attack is on the fruits of Christmas, things like alcohol abuse and promiscuity that increase during Christmas and all the other evils these lead to such as abortion, domestic violence and crime.
'We hope that out campaign will make people realise that Islam is the only way to avoid this and convert.'
Mr Rumaysah, who said his campaign was not linked to any group, boasted that the posters would be put up in cities around the country, including London, Birmingham and Cardiff.
The campaign was highlighted by volunteers from a charity which distributes food and presents to pensioners and the lonely at Christmas.
Sister Christine Frost, founder of the East London Neighbours in Poplar charity, said: 'The more posters I saw, the more angry I got.
'Someone is stirring hatred which leaves the road open to revenge attacks or petrol bombs through letter-boxes.
'I told the Mayor we are all scared.
'If we said such things about Muslims, we'd all be hanging from lamp-posts.
The poster itself is stupid; but the intent behind it is not. It is a slap in the face; a proclamation that a Muslim may say or do whatever he wishes, but the infidel had damned well better keep his mouth shut.
I say no. I'm not much of an artist, but I know some of you out there are. Would the design of a poster maligning one of Islam's rituals, such as the Haj or Ramadan, or Eid al-Fitr be OK with Islamists? Would they express their offense as the Sister did, or would there be blood in the streets?
I think we all know the answer to that. Let's see if freedom of expression and speech is a one way speech, shall we?
One-third of Muslim students in Britain say killing for religious offense is justified. No worries there, eh?
Make sure not to even say ham around a Muslim, or Interpol will come a' knocking.
