Democracy and Socialism are not mutually exclusive. Since FDR we have been living in a mixed Capitalist/Socialist Democracy. The crowning achievement of his career was "saving capitalism" since the Great Depression was setting the stage for an overthrow of the oligarchy. By mixing in Socialism he effectively headed off the revolution and the powers that be were able to maintain control, much to their annoyance. You see, the ultra rich live in a bubble and at some point become completely isolated from reality. They would have been very confused when the angry mobs dragged them out of their Newport mansions and strung them up from the nearest tree, because they honestly believe they have things in control and allowing workers to have Social Security, 40-hour work weeks and child labor laws would be unacceptable compromises.
Fast forward to today and we have a situation where the New Deal has almost completely eroded and the last vestiges of democracy were flushed down the toilet with the passing of Citizens United. The elites won and now naked capitalism is free to run it's course to exhaustion and collapse.
In that sense Bernie Sanders is actually a conservative, since he isn't really proposing anything radical or new but just wants to stick to the rules that were already on the books for so many years. On the Republican side we have various shades of Neo-Liberals who want lots of foreign intervention, dismantling all worker protection, and making trade deals like the Trans Pacific Partnership that evaporate our sovereignty to multi-national corporate overlords, which is basically everything you say you are afraid of when you use the word "socialism".
But if you confused socialism and totalitarianism it's easy to understand why you would confuse conservatism with corporate oligarchy. The media has understood the importance of controlling language for a long time now. That's why banning the Hawaiian language was an act of political sabotage and (arguably) genocide.
