Yes, there is great doubt. No Marxist movement has happened in secret because Marxist movements depend on the support of the people. That is the way they differ from movements of the political right. So the question is, do you see people in your state and community working with and joining an organization that calls itself "Marxist" or "communist" or "socialist"? No. Such organizations are few and small, and people aren't bothering with them.Let's go to the source:
Is there any doubt that today's "left", and sadly much of the "right", is headed down this road?
Secondly, the question is not whether we see the abolition of land ownership happening, which we don't, or whether we see a heavy progressive income tax, which we don't as the top bracket has consistently come down since about 1970, or whether we see abolition of rights of inheritance, confiscation of immigrants' possessions, centralization of credit and communications in the hands of the state, or any of your other "points". The question is whether we see some monolithic national organization advocating a people's revolution. We don't.
In fact, your post is so absurd that I recognize that it could be facetiousness, sarcasm, or an intended joke.
