So we should accept your "facts" with a "straight" face...? :-)
At least the V party stopped being Stalinists early -- directly when Moscow told them that Stalin was bad...
At least the Vänster party started early to harshly criticize the dictatorships in East Europe -- in 1989...
Let us talk about money and cultural exchange with dictators? Or about suppressing the information from the few surviving volunteers that went to Soviet in the 1930s? (Which did continue after 1989.)
At least V isn't changing opinions always whenever the wind changes -- not even after 1989 have they ever supported a democracy against a dictatorship!
And so on.
That is normal and "not extremist" in your definition?!
Thanks for a good laugh.
