Heilein's idea (later) of not being sexist was to write women being exactly like men

Then why did he say: Men are more sentimental than women. It blurs their thinking.?

...But then again he did say some good things:

Such as:

Rub her feet.

History does not record anywhere at any time a religion that has any rational basis. Religion is a crutch for people not strong enough to stand up to the unknown without help.

Never frighten a little man. He'll kill you.

Political tags--such as royalist, communist, democrat, populist, fascist, liberal, conservative, and. so forth--are never basic criteria. The human race divides politically into those who want people to be controlled and those who have no such desire. The former are idealists acting from highest motives for the greatest good of the greatest number. The latter are surly curmudgeons, suspicious and lacking in altruism. But they are more comfortable neighbors than the other sort.

But enough. Google "notebooks of Lazarus Long" and decide for yourself.
