'Cause i wanna be Anarchy

I was trying to educate myself on a topic i'm quite ignorant of, anarchism. But after all the readings i have come across, none make an argument that is understandable, non-hypocritical, and non-class biased.

http://www.infoshop.org/faq/ tried to explain anarchy to me, but i came up with the following problems:
"It allows working class and other oppressed people to become conscious of our power as a class, defend our immediate interests, and fight to revolutionise society as a whole. Only by doing this can we create a society fit for human beings to live in. "
-Why would the working class be concerned with power? Anarchy is to get rid of our want for power because it leads to heirarchy.

"Remaining disputes would be solved by reasonable methods, for example, the use of juries, mutual third parties, or community and workplace assemblies"
-Don't we use juries and mutual third parties to resolve conflicts in our capitalist society?

"Although many anarchists reject violence and proclaim pacifism, the movement...is anti-militarist, being against the organised violence of the state but recognising that there are important differences between the violence of the oppressor and the violence of the oppressed...As Malatesta put it...violence is "justifiable only when it is necessary to defend oneself and others from violence" and that a "slave is always in a state of legitimate defence and consequently, his violence against the boss, against the oppressor, is always morally justifiable."
-So you oppose capitalistic war because it is mostly provoked by power and the economy? Allowing violence from the opressed to the opresser is based on lack of power and is done to eventually succeed at having a more equal economic state. The reasons are the same-just at different levels. Why is one level better than the other in an anarchist's eyes?
