no one has said that! if you have a c section you have still given birth imo, if you need help to get pregnant then why wouldnt you still be normal, you needed medical help, people need medical help for lots of reasons that doesnt make them abnormal.
as someone who was lucky enough to conceive easily and have easy pregnancies and births, i consider myself just that, LUCKY and it doesnt make me more normal, or anyone that needs help less normal, why the hell should it? I am donating eggs next month, to give to a couple that need them to have children, i dont consider the people i am donating to 'abnormal' they are just people that need a bit of help, that i am fortunate enough to be able to give.
as i said thumbwitch put it better than i did :)
