Agreed on your first point.
Regarding when you go to UK and work there, yes, there will be racism (just like here on hive, and at home); but there will also be people of all color and races who will invite you to be their friends with open arms. And their numbers will be far higher. Do you know why? Because there are more good people in the world than bad. That is a fact.
No one can be more racist then us, people of the sub-continent! LOL. Imagine if 70% of doctors or any other profession for that matter is from people from sub-saharan Africa in Bangladesh, how would the population react? It will be total anarchy well before that.
However, that is the fact in England right now. And the country is doing okay, considering the circumstances. They are wonderful people, modern Brits are! Most of them will invite you with open arms. I assure you, that you will enjoy that multicultural melting pot, just like I do.
This is the hope we go by dada! I guess it comes down to what you originally said, the good people need to be more exposed, more vocal and not let the propagandists carry on unopposed.
