Dictatorial power? No. We have a vote on anything proposed, and a veto on anything we don't like.
Forcible suppression of opposition? No. Members disagree and use vetoes all the time without any 'punishment'.
Strong regimentation of society? No. The 28 members can run their own societies as they choose.
Strong regimentation of the economy? To a certain extent, yes. It's a European Union. Playing by the same rules is what makes it tick, although some members bother more about obeying the rules than others (France).
So, the EU is not an authoritarian and nationalistic right-wing system of government and social organisation, nor is it characterised by the factors you list, barring (possibly) the last one. Hardly a strong case for calling the EU fascist.
