Thought about it.  It's not bitterness, but disdain.  I'm disdainful toward women who are so small as to teach her children that sitting on Santa's lap is to be subservient to a man, and is an acceptance of male-dominated patriarchy.  What a load.  From what you say, it's your daughters who are bitter man-haters.  And if all goes according to plan, that's what they will raise.
