Marxists and anarchists get along far more often than not, the problems arise when one group takes up arms against the other and fighting ensues. Given that Marxists have had more success establishing systems, there are more examples of those minority of anarchists taking up arms against the Marxists. Marxists and anarchists may take opposite approaches, ie collectivization instead of communalization, but history proves that the two groups can and do work together far more often than not.
