With regard to the criteria of socio-political objectives, which are aspired
to by political parties, one can distinguish between those parties that seek
social or political changes in the frame of the existing democratic order
and parties that strive for changes by radical, extremist or revolutionary
means. The first group is composed of conservative, liberal, Christian
democratic, social democratic, in-part socialist, and also parties that define
themselves by religion or confession as long as they do not represent
extremist positions. To the second group belong mainly extreme rightist
or leftist parties and among those the communist parties, beside others.
