It is much less about ideology than the old days, no doubt, but not at all? I'm disagreing there. It's really only true if you see ideology as a purely stativ thing.
But that really doesn't matter in this discussion. I'm just pointing on a slight flaw in the pro/con-communism discussion that you and Olympian1010 were having. Overall I agree with you, but I do see ways to defend Olympian1010's ideas.
Mao didn't run on a "pure communist agenda". He did make it sound like it, but just as other self-appointed communist leaders he used the idea without really considering the people that it should in fact help, just like we would see in any new communist state.
Secondary, you can always find something positive. The good old "Hitler was terrible but he did afterall..."-comment (fill in the blank) is seen from time to time. Nothing is black and white and though the bad things did without doubt overshadow the slight good parts, if you search long enough, some statistic could be positive. Cherry-picking is afterall something plenty of groups like doing nowadays. The society doesn't work that way, but it can still be an interesting excercise.
There will always be firm believers in different ideologies.
