So, in my Fictional Axl Rose story, my Fictional Axl Rose is gay and the real world Axl Rose is straight. On another Website where I also have the Fictional Axl Rose story, a Poster said something like,"Axl is a Member of this Website. I hope he sues you for making his fictional counterpart gay when he is straight in real life."

What is the possibility that the real world Axl Rose could/will sue me for making my Fictional Axl Rose gay? :/
