The little I've read about Maines indicates she's been a hot head with an axe to grind all of her life. It's a bit remarkable that the other Chicks go along with it. Who knows, maybe they are scared of her.
That act like they share her lib views though not as shrill
Their management here are libs as well
I think Maines is ignorant more than anything
but, the Chicks were not too much till she joined with her quirky vocals and presence...admittedly
