This is what worries me the most about the direction things are heading - people seem to have increasingly strong opinions on important subjects they appear to have done zero independent research on. So we get arknor convinced that people who can just rock up and claim benefits for the lulz without bothering to check his facts - I'd like to hope he wouldnt cast a vote based on these assumptions but...
There is absolutely nothing wrong with sitting down, considering the facts, educating yourself as to how the EU works and then deciding that on balance, you don't think it's a good idea and you think the UK would be better off outside of it. This is a rational, considered opinion.
There is everything wrong with the current trend of reading crap stories on rubbish newspapers, listening to other people spout BS and then deciding immigrants are the fault of everything, the EU sucks, and deciding we should be out of it as a result.
Both of those thought processes have the same net effect but IMHO only one is valid. Trouble with referendums and the like is the latter will dominate the former.
