I agree and sympathize -- insofar as you accept that you've taken nothing away from the original posting.

Sexism cuts in both directions. IMHO, M-to-F sexism is much more prevalent, more damaging (for example to women's career prospects), and a more serious issue, but as you complain, F-to-M sexism is real, is (in some circles) more widely socially acceptable, and is sort of insidious. I admire it when men or women stand up to either sort of sexism.

I especially admire this woman's stand. She stood up alone, in a room full of men who had laughed, and calmly demanded to be treated with respect. I submit that she's a role model for anyone who faces discrimination of any type and any severity.
