forcible suppression of the opposition - Hmm, IRS, EPA, OSHA, scandals, but Nixon did the same as did LBJ. Still not left or right, but both parties seem to like this idea. How many on this site want to end Limbaugh's, Hannity, Madow or Shultz's career of spouting the party line on their shows because they have a different political philosophy.
Private economic enterprise under central governments control - this one is all left. Yep, definitely left.
Belligerent nationalism, racism and militarism. Probably both parties again as each party views the other party as being unpatriotic, racism, the divide the people up into groups, by race, sex, religion and more to divide and conquer in the search for votes, to make one group hate another group if that brings in more votes, yep, both parties again. Militarism - it is the same song and dance, a war under my parties president is good and a war under the other parties president is bad.
I suppose fascism is neither left or right, Republican or Democrat, but I think both parties dream of being in power and in control like any fascist would.
