How do you handle racial issues? I'm not talking in game btw. I have a party of 3 white guys, one white woman, and a black woman. Last session one of the white men (who was a custom race ghost) possessed the black woman's body and made her rebuild a church she had burned down.

The session before the black PC decided to burn the church of the morning lord in the Village of Barovia to the ground because she was mad at Donovich for not allowing the party to kill his vampire son. (The issue was slightly more complex but that's the gist)

The ghost PC who possessed her (who was absent the last session) was a follower of the church she burned down. Being pissed, he possessed her with a successful wis DC. At that point I looked at the rules and realized she had no way to escape unless she hit 0 hp.

Immediately I realized the issue with allowing a ghost PC. I allowed him to control her long enough to save the temple, but insisted he release her after.

Later she said her character planned to leave the party and she would make a new one.

After she told me she felt trapped as a black woman controlled by a white male. It triggered strong PTSD feelings in her. I Immediately apologized and smoothed things over, but I'm afraid I made a nightmare level error.

How would you handle this and how can I be more sensitive to racial issues as a white DM?
