"You must be the change you wish to see in the world." - Mahatma Gandhi
That is all.
but then you get people like this one acting out the change they want or indeed those that wish to see the UK under sharia law 
“By the skillful and sustained use of propaganda, one can make a people see even heaven as hell or an extremely wretched life as paradise.”
― Adolf Hitler
But those would be deluded to believe that was the best thing for the human race. People who want it their own way regardless what others think or how it would affect them are obviously all what is wrong with the world. You have to ask yourself, 'where would the world be if everyone thought like me'. I'm pretty content in thinking that if everyone thought like me we would all get on much better. Of course its dreamland territory to think this is possible but at least I have made the relevant changes and rid myself of all what i feel is damaging to a global society. I used to be a racist, homophobic, religious, ignorant, queen loving patriot. I don't care for it much now however and that's a big change to make in a country where its pushed down your throat. You can't help how your brought up but their comes a time in your life when you have to start thinking for yourself and stop being manipulated. Ridding yourself of the barriers that have been put up that tries to divide you from the rest of the world is a very important step I believe.
You can only change yourself, not anyone else.
