It is not demeaning to be identified as a woman by such terms and you should question the mentality which prohibits them. Always have been. Femspeak is a feminist attempt to blot out this fact. Feminism is a form of collectivism which seeks to divide mankind into warring factions based on sex, just as Nazism sought to divide mankind into racial factions, and Communism sought to divide mankind into economic factions. Feminism no more seeks fair treatment for women than Nazism sought fair treatment for Germans.
Collectivism promotes collective guilt.
Males are to be targets of discrimination, subject to quotas and legal disabilities. The Nazi parallels are obvious. Collectivism needs a fundamental Big Lie, and feminism's is that women have been systematically excluded from mankind, that virtually everything from reason, to law, to marriage, to the forms of language is a male plot. For example, they can claim that the philosophers who upheld the 'rights of man' meant to exclude women. The inclusive use of 'man' is a barrier to such re-writing.
