Question for the Trans community

Ju

Hey Everyone! Quick question if you don't mind. I've been trying to grasp this for a while and I don't really get it and I'm hoping maybe someone here has a spoon for me! If not that's totally fine and I'll keep reading on it.

If a person recognizes transwomen as women, but acknowledges that they have different experiences from biological women due to their past, why is that considered transphobic ? Thank you.
