Just to be clear: I wasn't trying to make a joke at the expense of women getting their periods. Most men (at least, any decent ones) have sympathy for the biological reality of women enduring menstruation. We just are physiologically incapable of experiencing it ourselves, so we can't be faulted for NOT KNOWING how it feels.

If, by "female sexism," you mean "misandry" -- agreed with you completely.

But, apparently, misandry doesn't even exist. Because a bunch of sociologists say so...
