Calling facism a right-wing ideology doesn't make sense because facism at its core is the anithesis of conservative values (small government, freedom of the individual vs. extreme governmental control, no freedom of the individual). And when you actually compare facism and communism side by side, you would see that both ideologies are actually pretty similar except facism has a stronger emphasis on nationalism. Honestly, anarchism would make more sense as a far-right ideology, because that would be taking conservative beliefs of individual freedom to an extreme form.
