Earlier quoted context omitted.
Then there are the democratic socialists, who are actually socialist (unlike the social democrats) but who disavow Marxism-Leninism. Problem is, assuming you set up a democratic socialist regime, if you want to keep the democratic bit, you risk losing the socialist bit (and vice versa). A lot of demsocs don't realize this; many believe that democracy and socialism are completely coterminous with each other.
One counterpoint is that a lot of social programs are hard to get rid of. Even though the right campaigns against new social programs sometimes, there’s no way they can convince their electorate to get rid of existing social programs. For example, there would be very little political will to get rid of government-provided unemployment insurance, even though right-wing rhetoric is often against that sort of program.
Not everybody will be convinced that this will lead to the promised paradise of maximal creative freedom and abundance for all, so not everybody in a democratic system will vote to continue socialism and there's a risk that a majority will not! Well, that is, until the kulak purges begin.
