I think the reason people rip on Carol is because she's made outrageous claims (I've read somewhere that the artists and engineers that were on certain recordings she claims to have been on have no recollection of her being there), she says outrageous things (the whole people-don't-teach-musicality thing), she gets defensive when questioned, etc. The point is, she's a controversial figure so she sort of invites criticism. I personally find it absolutely ridiculous that someone who claims to be this amazing bass player can't be bothered with changing her strings. So, yeah, she deserves to be ridiculed for that. If I didn't know how to change strings, could only play with a pick and ripped on people who could play different ways, claimed I played on a bunch of famous songs that no one remembers me playing on, flew off the handle at the slightest criticism etc... I would be inviting a backlash and criticism too.
Just my 2 cents.
