Fascism is when the government and the corporate interests are gelled, so that the government exists to carry out their whims, rather than actually serve the people....this is why it was referred to as "national socialism" by the WWII era dictators.
Democratic socialism, as practiced in Scandinavia, and to a lesser degree in Australia or NZ (this is using a strictly American definition, which essentially means anything left of an American democrat) is built differently. There are usually very strict limits on corporate power, with a more expensive safety net.
I am not in favor of either, but these are only similar in theoretical comparison....I would like to think most Europeans, those that had their countries invaded and destroyed by Fascism, would take quite offense in claiming their democratic socialistic system was a "type" of fascism. One puts growth and industrialists as kings of the world (I.E. the famous Oskar Shindler was not even a political man. He was rich though, and that is all the power required), while the systems that replaced them in Europe put strict barriers on such direct oligarchy.
Gov forces you to buy their product, which they will disproportionally price on the wealthy = socialism
Gov forces you to buy from a PRIVATE company that they allowed huge influence into writing the law you must now follow = fascism
