Oh, I understand history very well. Socialism like liberalism is always sold as a way to help the poor and the children and the old because who can be against helping the poor, the children and the old? Remember all of the pictures of Hitler (since you are reading scholarly texts about Hitler) with the youth?
The problem with socialism/marxism and communism is that it runs counter to human nature. Oh, you will always have takers who are willing to demand that others provide for them. We see it here on a daily basis from JPP leftists. JPP is littered with leftists. But, for most, human nature is that we want to take care of ourselves first. We want to provide for our family. We don't want to have our property confiscated by the government to have it transferred to a taker so we resist. Well, noble "socialists" such as yourself can't abide by that. You see, you are convinced of your own self importance and aggrandizement. You ask yourself "How could anyone be against me taking their property so I can help the poor, the sick, the children and the old?". You convince yourselves that those who resist you are "evil" and "greedy" and whatever other derision you can throw their way. But, you won't accept human nature, so you eventually turn to force. You will not abandon what you believe to be "noble" goals so you convince yourself that the ends justify they means.
That is why everywhere true socialism is tried, it leads to violence, destruction and poverty. Oh, trust me I know history all too well. It is you who does not. All of the things you accuse Trump of being, the democrat party does and more. You just can't see it. You are convinced of your own moral superiority because you come to a message board and pompously proclaim that you "want to help the poor and the rich should pay for it". You think that somehow makes you a good person. It doesn't
