I am a man. There are a lot of things I can do. However, I can’t menstruate, get pregnant, give birth or breast feed. Neither can all the ‘pretend’ women. Time to get real.
Most trans women have breasts, and with the right hormones are capable to lactation, so we actually can breast feed. And so can you Sonof"Liberty". Male and female bodies are more similar than you think. I mean, you have nipples right?
As for menstruation, pregnancy, and giving birth, well, one day perhaps medical science will figure out a way to give trans women working uteruses. Somehow, I suspect that wouldn't make you accept them as women. Probably not even if sci-fi nanobots went in and replaced all the Y chromosomes with X's.
