The Nazi party was never a socialist party, the name is misleading. And Stalin was never a true communist, he was a tyrant who murdered any who opposed him. Don't be fooled by appearances; both might have claimed to be left wing, but were the exact opposite.
The traditional principles of righty government are essentially to seize power and oppress if need be, demanding that the public: a) don't object as they're too stupid, immoral, ignorant etc. to rule and b) trust the government. Essentially, right-wing politics doesn't even make some kind of pretence about "listening to the people", so in this day and age, it ain't gonna be popular.
