Remarkable "Supremist" attitude of early American Suffragette - Susan B. Anthony

I was surprised to learn that the masthead of the newspaper founded in 1866 by early American suffragette/feminist - Susan B. Anthony and Elizabeth Cady Stanton - was:

"Men their rights and nothing more, women their rights and nothing less". 

Which seems incredibly "female supremacist" EVEN now.

It seems clear - but even these "answers" seem to indicate there is a great deal of wishful thinking in interpreting it positively at the same time as disagreement about what it means.

No wonder it took until 1920 for women to get the vote.

Unfortunately - it NEVER ends.
