No I really havent heard of either one at least not that I recall Ive heard of extreme positions usually in a dismissive and ironic way but dont really know their details They really are on the fringe and not held by the majority of feminists Ive been involved with several feminist groups usually working on local issues but I am by no means a feminist scholar I only have a general knowledge about feminism and especially how it is practice within NOW of which I am a member I dont follow the literature for example    I am truly committed to maintaining a npov and I hope you are too Im not convinced of that though Please consider making an attempt to carefully state that the beliefs of certain subgroups of feminism are not necessarily beliefs feminists as a whole agree on Readers will make their own judgement about which beliefs they buy and which they dont It isnt up to us to steer them one way or another And have a Happy Holiday Dmerrill
