Diversity is basically not tarring everyone else of a certain group with the same brush. But that's what we all do, and what we always will do, and with very good reasons to do it.
If you have a positive or negative experience with something new, be it an object or a person, you will automatically tend to have a positive or negative anticipation towards the next object or person of the same type that you may meet. The more the experience goes one way or the other the more reinforced that impression becomes, so it's natural that once it begins to get negative you will begin to avoid objects or people of that group wherever possible and you may even start warning your friends to do the same.
An example might be wasps. Wasps tend to sting, not necessarily all of them but certainly most of them, so most people tend to hate the nasty little things. Of course there could be lots of wasps that don't sting but the experience of the bad ones naturally means that you don't want to take any chances, so you avoid them all like the plague.
And so on to our most recent trip to the Maldives where everyone I met who was a Muslim was really nice and friendly, most of the Russians I met were miserable and rude, and all the Europeans were fine.
Maldivians, who are mostly Muslim, are a very friendly bunch and are happy to stand around talking for ages if you let them. The problem is that life for them is so different than it is for us that it can sometimes be very hard to know what to talk about with them. Cars are something that men can usually turn to as an easy topic of conversation but a car in the Maldives is about as much use as a surfboard in Southampton, so consequently most of them have very few opinions and views on the subject. Sports works for some people, but as I'm only really interested in F1 and skiing I'm once again barking up the wrong tree. Anyway, they're all really lovely people and I've now convinced myself that this positive attribute obviously extends over the entire Muslim Maldives population.
Russians on the other hand can be a complete pain in the backside, and I'd say that from my experience the majority do seem to fall into that bracket. They are very rude by European and US standards rarely thanking anyone for anything and usually barking orders at anyone providing them a service, such as waiters etc. Every morning we would see Russians go to the omelet chef, grunt out the filling they wanted to him with no politeness, or even eye contact, and then, when he slid the completed product onto their plates, they would simply turn around and walk off. Not a word, not a nod, not any any recognition of appreciation whatsoever. Many staff told us that they hated the Russians for their rudeness but they do apparently spend a lot of money so are naturally welcomed trade.
The Europeans were all absolutely fine, especially the Germans who I always like and find very easy to get along with. The Italians were good fun even though they all seem to smoke a lot, have a very thin grasp of English, and appear to be scared of live fish. But they do all like to have a good time. That was about it for Europeans this year out of all the folks we spoke to anyway.
Finally there were quite a few Indians this year. They all seemed very polite but kept themselves to themselves. That works for me. If only the Russians would do the same and stay at home.
