Even if whites weren't the majority, I really don't understand why that matters?
We encouraged immigration when it suited us, so man up and embrace it.
I love living in a city with people from around the World, it's far more interesting than everyone being White British.
I agree 100% with the whole efficiency thing. If people are rude to you in London it's because you're being a mong. Probably standing on the left hand side of an escalator or something else unforgivable.
If the only really negative point that you have that holds any real weight is that the tube is busy and you can't drive, you might have to start thinking up new arguments bae. You get used to the Tube in about two trips and then couldn't live without it. Who wants to drive everywhere when the Tube means as many after work drinks as you want?
I'll just say Sue's post was 100% perfect.
