Some of us here on FR are perfectly aware of what the EU is and is not.
To make it very simple, what the EU is, it is a very autoritarian system, which bit for bit are bypassing our national democratic institutions.
If I want to fight against socialism in Sweden, I first of all has to make sure that it (in some form or other) is not imposed on us from outside.
And just as I wouldn't want socialism (or more socialism in the case of Sweden) forced upon us by an unelected elite in Brussels, I wouldn't want a free market economy forced upon us. Because such a thing wouldn't be free, and according to Friedrich Hayek, it wouldn't be a market economy either.
