Supreme Court, The New Proletariat?
If you think property owned by industry is more important than property owned by private citizens, you might be a communist.
"The distinguishing feature of communism is not the abolition of property generally, but the abolition of bourgeois property."
-- Communist Manifesto.
If people have become angry with your opinion that people should not be allowed to fully own property, then you might be a communist.
"We Communists have been reproached with the desire of abolishing the right of personally acquiring property as the fruit of a man's own labor, which property is alleged to be the groundwork of all personal freedom, activity and independence. " -- Communist Manifesto
If you think industry-owned property is preferable to private, individual-owned property, and that they ought to be left to their whimsical confiscation, you might be a communist.
"Hard-won, self-acquired, self-earned property! Do you mean the property of petty artisan and of the small peasant, a form of property that preceded the bourgeois form? There is no need to abolish that; the development of industry has to a great extent already destroyed it, and is still destroying it daily." -- Communist Manifesto
If you're not horrified by the Supreme Court ruling favoring seizure of private property based soley on industrial "utilitarian" gain, then you might be a communist.
"You are horrified at our intending to do away with private property ... In one word, you reproach us with intending to do away with your property. Precisely so; that is just what we intend." -- -- Communist Manifesto
If you think people are outraged only because they don't understand the benefits of this Supreme Court-approved arrangement and that their notions of morality only come from their pocketbooks, you might be a communist.
"But don't wrangle with us so long as you apply, to our intended abolition of bourgeois property, the standard of your bourgeois notions of freedom, culture, law, etc. Your very ideas are but the outgrowth of the conditions of your bourgeois production and bourgeois property, just as your jurisprudence is but the will of your class made into a law for all, a will whose essential character and direction are determined by the economical conditions of existence of your class." --Communist Manifesto
If you think all eternal truths are dangerous and must be abolished (preferring post-modernism), that "morality" doesn't have to be based on on historical experience and presidence, and that no one should be allowed any public religious expression, you might be a communist.
"But communism abolishes eternal truths, it abolishes all religion, and all morality, instead of constituting them on a new basis; it therefore acts in contradiction to all past historical experience." -- Communist Manifesto
If you think that government can better spend people's money than the people themselves and must take capital and property to more fairly distribute wealth regardless of the means, you might be a communist.
"The proletariat will use its political supremacy to wrest, by degree, all capital from the bourgeoisie, to centralize all instruments of production in the hands of the state, i.e., of the proletariat organized as the ruling class; and to increase the total productive forces as rapidly as possible. Of course, in the beginning, this cannot be effected except by means of despotic inroads on the rights of property
-- Communist Manifesto
