If someone is being trans phobic, you should report it. That's really not on.
If you are talking about women disagreeing that simply wearing a dress, growing your hair long, wearing heels and make up makes you woman. Then that's not transphobic. Do you believe you are only a woman because of those things? Do you believe women who wear mens clothes are men? What if they have short hair and dont wear make up?
If you are talking about women disagreeing that males should be allowed access to spaces that are for females only, simply because they say they identify as a woman. That's not transphobic. That's being concerned about women.
Or are you talking about comments that disagree that your swx doesnt change just because you said it did. That's a biological fact. Gender is a social construct. Your sex is not and is not dictated simply by how you present yourself. Or do you disagree with scientific fact.
I have never seen anyone on MN care if a men want to wear dresses. The exception being the wives of these men whose lives have been changed forever once they discover this. But generally, mners dont care. They do care they men can say they are a woman and get transferred into a womens prison. Especially when these men are already convicted rapists. Then go on to attack female inmates.
Or are you just being goady?
I suggest you friends actually look into the issues around it.
