>His viewpoint isn't okay
And yet you call upon him to act like an adult.
Anyways, I'd love to hear what defines a viewpoint as okay. Is it just the fact that it agrees with your viewpoint? I imagine you are some kind of authority on life who knows what every valid and invalid view is.
We need to send a message back to her that she is the one being drama and needs to grow up and be a 'real adult' like she says she is.
Honestly that just sounds threatening, it's not alright.
