I agree with many people that us Brits are *generally* (I shouldn't generalise really, but...) a bit more conservative when it comes to stuff like this.
Unfortunately, we also have some councils and such getting very PC over here. For example, I've heard that some counties have had problems with putting up Christmas decorations in town centres as the council don't want to 'offend' any ethnic minorities. I've got to say that this really REALLY winds me up.
I have a great deal of respect for other cultures, but these days it seems to be 'long-standing' Brits - I'm talking about those who have British ancestors dating back over 200yrs - are the ones who are being treated differently and, in some ways, unfairly. The worst thing seems to be that it's BRITISH councils who are imposing these 'no-Christmas-decorations-type' sanctions on us, NOT the ethnic minorities! It just doesn't make sense!!
BTW.. I do notice that a lot of people in Wales have stuff in/on their cars. For example, the Welsh flag on their number plates, flags in the back windshield, red dragons, etc. And we still have daff's and leeks on St. David's day (and dress the little girls up in their 'Welsh costumes' - I believe that the shop in the UK in EPCOT has some assistants who wear this!). And half of my street had the flag (Welsh flag obviously!) flying during the Six Nations earlier this year!
