At this point it's basically a part of Porsha's pattern to interject herself into issues that have nothing to do with her.
It's happened with Phaedra and Kandi, Kenya and Nene.
She doesn't know how to be objective and stay neutral. She always has to "pick a side", but gorl no one was really asking you to.
It's testament to her lack of intelligence and her immaturity, tbh.
