in my opinion, the question isn't "Is RPF ethical?" but rather "Are you engaging with RPF ethically?" and even more importantly, "Are you being stupid about it?"
I personally hate any kind morality thought policing. I'm not Catholic or religious and I do not feel guilty over my thoughts. You are not an inherently evil person because you saw two athletes in an interview and went "Hmmm...... what if...." The Feds are not going to come banging down your door because you wrote about one band member dicking down the other and sent it to your friend.
Wondering about other people's lives is very human. Being nosy about their personal lives is very normal. People have been writing fiction about other people's lives since the dawn of time. Some people even manage to write New York Times Bestselling Books that are "historical fiction" or "alternate reality." It does not make you inherently bad to be curious about the details of someone's personal life. That's being human. Being nosy is kind of fun.
The problem, however, comes with the ways in which people engage with it, and involve the real people in this. Harassing an musician's real girlfriend because it doesn't fit into the RPF ship. Showing up at real sporting events holding signs about how certain teammates should kiss. Trying to get actors to sign art of them fucking their coworker. Flooding social media with comments using the celebrity's full name and speculation. There's a line, there's a fourth wall, and there's fandom etiquette.
I hate the question of "Is RPF ethical" because it feels like morality thought policing. Post your fics on locked accounts, censor someone's name when you tweet about it, blow up your groupchat with hundreds of "DID YOU SEE THE WAY THEY LOOKED AT EACH OTHER??" texts. It's not inherently evil to wonder what other people are doing when they're out of the spotlight. Kill the cop in your mind.
But just have some basic decency and do not involve the real people. Don't cross the line without caring how it affects them. This is basic fandom 101 and lately we have been flying too close to the damn sun! Everyone get more normal about RPF so major news outlets and magazines stop posting articles about "Is RPF ethical?" and blowing up our spot!
