Dear Rosie,
Hello! Much respect for your understanding and whatever way you choose as being right for your heart.
I come back to a saying of Ajahn Brahm’s: if there’s something you can do, do it; if there’s nothing you can do, then do nothing.
I think all systems and ideologies are flawed because we are. There bound to decine.
But if there’s some small thing to be done to reduce the harm in this world, perhaps, without any hope or expectation, it is worth doing. At least we know our intention is pure.
I want to post some links but might link them to some new topics so they don’t get lost at the end of a long thread. But dear @moderators, if you deem them inappropriate topics, please feel free to remove or lock them. 
Much love Rosie
