JAPAB - Womanhood is biology and life experience. These are broad groups, at least some of which are shared by all women. Transwomen share none of these with us women.
Biology : Women are adult human females, just like cows are adult female cattle, hens are adult female chicken, and does are adult female deer. Transwomen are not female therefore they can't be women.
Note: FEMALE is a biological description that means OF they sex that CAN bear young or make eggs. A woman who has had hysterectomy or is sterile for whatever reason is still female as she is of the sex that can bear young or make eggs, as opposed to the sex that can make sperm. FYI, we call the latter MALE.
Life experience : As a man, you are obviously ignorant of what this entails. It means we are raised differently even in the most liberal families, and experience sexual harassment from an early age. We are groped, attacked, held down, ridiculed, talked about as sluts for daring to have sex. We quickly learn to minimise these risks. Our opportunities are relatively limited and shaped by expectations of future motherhood. Even the very few of us who don't have functional reproductive organs are treated in this way. Transwomen don't share this life experience with us women, either.
Do you understand now that you are talking nonsense with your "But some women have had hysterectomies so transwomen are women too"? If not, I have some free time today and am feeling generous, so let me know and we can continue with your education at your leisure.
