I guess I don't find these jokes funny. Everyone should be free to live their lives the way that makes them happy. Who am I to judge?
I think both ideas are true. He/she/it is free to live his/her/its life as she/she/it sees fit, and I'm free to comment on that life as I see fit. That latter part includes making fun of it. But I'm equal opportunity, and if he/she/it wants to make fun of my life choices, I won't argue.
