Hi Isabelle,
I don't know, you may be right. I think some version of Buddhism states that just because one life is shitty, that's because you're there to learn something or master something, so the next life may be an improvement. Just because one person was abusive to you in this life, may not mean they'll be abusiive to you in the next.
Usually the comments I hear when someone has treated me or someone badly is that 'You must have done something bad to them in a previous life' which, of course, is not reassuring.
As for anarchism, most of the stuff I've read about them follows these definitions:
# The theory or doctrine that all forms of government are oppressive and undesirable and should be abolished.
# Active resistance and terrorism against the state, as used by some anarchists.
# Rejection of all forms of coercive control and authority
Which of course means that anarchists don't believe in democracy, they want to overthrow the state no matter what it is, reject teaching institutions of all kinds (political/secular/religious), and believe that violence is perfectly justifiiable in pursuing their causes, etc., etc.
Like I said, not very nice people.
