Some argue it was intentional

Yeah, that "some" are the Nazis and other rabid anti-communists with zero evidence

most seem to think it was a degree of both of those

Given the fact that all serious historians admit there is no evidence of any intent, that is a bare faced lie.

Let's not rehash this same topic for the millionth time, it's been discussed ad nauseam: https://lemmygrad.ml/post/1155

What never ceases to amaze me is the sheer shameless hypocrisy of anti-communists. So quick to attribute every problem in socialist countries to socialism or its leaders, yet when something of equivalent magnitude like the Great Depression happens which also produces millions of victims you never attribute it to "colossal mismanagement and incompetence", let alone genocidal intent. Even when such intent is quite clearly demonstrable like in the famines in colonized Ireland, colonized India and many other instances in the global south where colonialism, imperialism and capitalism have and continue to murder many millions more than socialism ever has... But under capitalism that's just an unfortunate natural occurrence i suppose.
