2. Well you're free to disagree, but the point remains that capitalism is comparable, if not worse, to other systems (namely state capitalism / "communism") in regard to responsibility for deaths and suffering.
About your final sentence, first of all you apparently have no clue of the ideologies you're talking about. Claiming anarchism (for instance, but the same can be said on communalism and many others) is the same of communism in regard of authoritarianism and human rights is plain misleading, as being anti-authoritarian is like the main point of anarchism.
And the point in anti-capitalism is not about being against people who are rich, but being against the fact that they are rich while other people are extremely poor. Nothing against people themselves (I think everyone would be happy to be rich), the problem is that the system is so fundamentally flawed that some few people can own more than billions of other people combined.
