Heilein's idea (later) of not being sexist was to write women being exactly like men (never too busy for a little squeeze-titty etc). That is sexist to me, I like my women womanly.

But then again he did say some good things:

"Women and cats will do as they please, and men and dogs should relax and get used to the idea." (still sexist but I like it.)

"The universe never did make sense; I suspect it was built on government contract."

"Yield to temptation. It may not pass your way again."

Then here are some more from Ingersoll:

"If a man would follow, today, the teachings of the Old Testament, he would be a criminal. If he would follow strictly the teachings of the New, he would be insane."

"Tolerance is giving to every other human being every right that you claim for yourself."

and

"Anger blows out the lamp of the mind."
