The father didn’t “lose” anyone. His daughter is still right there, he could have a loving and close relationship with her if he chose to accept her for who she is. He didn’t lose his son, he chose to reject his daughter.
Choosing to not support your children is how you become estranged from your children, not something to feel sorry for the parent for. It just makes the father a piece of shit. This statement is true of all shitty parents, not just transphobic shitbags.
This is so emotionally manipulative / abusive, and says everything anyone needs to know about reddit/spez. It's like if someone burns down your house and says "look i'm here to acknowledge that your house has been burned down, but we can still work things out bestie <3"
