Why are there more fascist anti-imperialists than left anti-imperialists in the West ?

The alignment of anti-imperialists with the fascist far right now seems firmly established in European politics if not US politics as well.

No where is this better illustrated than in German politics, where BSW party nearly got a seat in federal government, whereas MERE25 is nowhere to be seen.*

The way the story is told in mainstream US media is that right wing parties (deplorable) propose abandoning NATO (outrageous!!!).  Never ever is it mentioned that there are left movements, parties, and histories that also opposed NATO from its beginning and still.

(*Germany should not even be considered a representative democracy because the one party that could maybe challenge capitalist rule has been banned since 1956.  The Communist Party was never banned as such in the USA, and ran candidates in US Presidential elections until 1988 after which it decided not to anymore.  Individual Communists, however, were often persecuted by federal and state governments until freedom of speech was clarified by Brandenburg v Ohio in 1969.)

 Melenchon was originally anti-NATO, but now a serious person (as in the rightfully elected) he's become pro-NATO.

Liberal and left leaning people are not permitted, if politically visible, to be anti-Imperialist.  Even though much of the public feels that way, on both counts, they are not allowed to express either sentiment purely (they must instead vote against impending fascist oligarchy and for a weak "liberal" candidate who will basically do nothing to change the status quo for the better) and especially both at once.

But what else should we expect from a fascist capitalist oligarchy?  They're fine with anti-Imperialism, or populism, but only if it's Fascist.

Left anti-Imperialism is in the kitchens, and on the streets, but it's never on TV, in the corporate press, or acknowledged much elsewhere.
