MJ already had her moment,and besides,she's married to the actor,and now it's time for something new. Also, I'm not racist;I have Black friends and I don't judge them by their appearance. I don't know why,but Jean and Peter should be together because it's an interesting dynamic.
It's hard not to think the reason why Peterjean is a thing is because people are still butthurt that MJ is played by a black woman and not a ginger so they wanna force a ship when Peter interacts with the first ginger he meets.
