Here's an article about the Soviet terror-famine (known as the Holodomor) which killed 4 million Ukranians. No worrisome notifications on this article, so I assume it meets your rigorous standards:

And here's one about the so-called 'Great Leap Forward', when the Chinese Communist Party's top-down modernization plans resulted in the accidental deaths of ~50 million human beings.
Here are a few examples off the top of my head:

* Though I will object that it is unfair to attribute the actions of the Khmer Rouge to socialism. Like the Nazis they were socialist in name only, and in fact were supported by the United States in their war against the Socialist Republic of Vietnam.
EDIT:. I'm not saying what's normal is ok, I'm saying what's common is more likely to falsely correlate with anything. Whereas as the common factor for communism across the board has been a high statistical propensity for mass murder and genocide. This includes the nazi regime I might add (look it up)
Just because something is the "default" option doesn't mean it is non-ideological. Ideology is a powerful tool for shaping people's actions. People will go along with insane and sometimes horrifying things just because they perceive them as "normal". Maybe expose yourself to some alternative ideology. You don't have to agree with it to learn something.
The only difference as a result of ideology was the timeframe. The USSR was forced to rapidly industrialize due to global pressure from foreign militaries and famines in China were exceedingly common long before communism.
History is not as simple as you're making it out to be.
I'm not a maoist, so I'm not about to defend his ineptitude, but it seems intellectually lazy to point to these problems as unique. In the 18th, 19th and 20th century, depending on what level of development a country was in, these problems were widespread across all ideologies.
Think about why Stalin is presented as a terrible leader and Churchill as a great one.
Obviously the name of an organization doesn't mean jack compared to their actually implemented and enforced policies. The first things the Nazi's did when they gained power was kill all the socialists, communists, and unionists. They are anything but socialist.
"We are socialists. We are the enemies of today’s capitalist system of exploitation … and we are determined to destroy this system under all conditions.” ~ Hitler
Communists were among the first inhabitants of Hitler's concentration camps. The Communist Part of Germany started the organization Antifaschistische Aktion, the direct precursor of what we now know as Antifa.
And please stop equating "anti-capitalist" and "communist". The two are not the same or even close.
Global deaths from hunger result in one great leap forward every 5 years.
After all, it's a simple matter of fact that the accelerating decline of global poverty since 1990 was the result of the transition to capitalism in formerly Communist/Socialist countries in Asia, including the CCP's own particular flavor of state capitalism.[0]

There are only countries with specific sets of laws governing them. The question is which system of laws is better and why and when and most importantly: Better for WHO?
Arguing that capitalism is the solution is like saying: Don't look here, we are better than socialist countries and therefore there is no need to improve anything in our country. Same for the other side too.
