Yes they've had to knock their corners off to fit in with the mainstream... That's not to say that they don't have those principles still at their core. Look at the type of people drawn to UKIP, the 'every man is an island' middle englander, essex man and far right thug.
Everything they stand for is regressive, 'let's go back' how many times have we heard this phrase from Farage?
Liberty – People living their lives as they choose with government off their backs;
Democracy – elected representatives work for the People, not the party and promotion;
Justice – fairness, social justice, rule of our laws, upholding the People’s rights;
Prosperity – through free enterprise together with prudent and honest government.

Meaning? Privatise everything, and get rid of any regulators that might spot exploitation and bad practice.
Yes UKIP want you to live your life as you choose... unless you're gay and want to get married and have a family, then it's a no.
