Here is a single credible reason.
I am not a racist, in fact I have had black girl friends, gay relationships, multiple partner relationships. I have muslim friends, hindu friends, budhist friends. I myself am agnostic and spent two years living in Europe (Portugal) and travelling through it.
I did not vote to leave the european union on the basis of immigration or ANYTHING to do with it.
I vote to leave the European Union because it is undemocratic and it's run by people who for the last 150 years have spent every second of their energy to push and produce the european union in the way it is.
The EU is backed by the IMF and works closely with the World Bank. It's inhenrently corrupt and takes bribes on the most rediculous of levels to pass laws and legislation that allow CORPORATIONS to take control of your own countries laws, regulations and policy.
Did anyone ever stop to look at TTIP (Transatlantic Trade and Investment Partnership) which came DIRECTLY from the United States to Europe. The US economy has been slowly westernising the EU for the past 50 years. They have been fighting to push this legislation in for eternities. IF you bother to do even a little research, you see what this legislation does. Creating a police state and Corporate controlled laws and business practices that DIRECTLY undermine anything the EU stood for.
Leaving the EU stops TTIP. Leaving the EU fights coporations. Leaving the EU shows people like the IMF we are not afraid and we won't pay for the debts or mistakes bankers made for our system.
What the conservatives ever do in the last 5 years in a unified UK with the EU. They cut the social welfare bill by 20% killing millions of helpless and disabled people. They moved the biggest amount of PUBLIC money into PRIVATE pockets you've seen in nearly 100 years. They had the most corrupt MP's you've seen in at least 35 years. With David Camerons earnings coming into controvesial and serious questioning due to his fathers ethics.
The current UK has no faith, the people have lost interest and the people calling us racist for doing so are doing it out of a fear of change.
People are so quick to judge and generalise and entire collective of people.... a collective is a collection of INDIVIDUAL opinions, this does not mean the entire group is racist. SOME of it is racist, yet some of the opposition is probably racist too.
Your own god damn EU loving Prime Minster is a fight for the rich man give no shits about anyone else kind of character, yet you have the balls to call thought out and education opinions racist. Cowards. Go back to your facebook and troll forums. Think for yourselves.
