You can call me a Brit. We call outselves Brits. And when we gang up together overseas we are happy to call ourselves 'Brits Abroad'.
Must say I am bothered at the above stereotyping of Thailand as a Sex Tourism resort. Sure it exists and is a real, problem - but then it is in Las Vegas too! I deffo got more flyer for hookers in my vegas hotel than I did in Bangkok!
Stay away form the Pat Pong area in Bangkok and you find incredible islands hosted by relaxed people who understand what service is, incredible diving, outstanding jungle - real culture, mouth watering food, and all very, very cheap. Add to that the contrast between the weather there and the weather here in Europe and you don't need to go look for sinister motives for so many Europeans to be in that fantastic country. I have had two vacations there and (before the damage) recommended it to anyone who asked!
My son was born in England
part of the United Kingdom of Great Britain.
I never would think of calling him a 'Brit'.
I guess I am an old-fashioned, proper Canadian.
