Jean said "I remember hearing a story of when the MRA was first brought up. A man named James Walker came out as a mutant and supported the act. He was a respected man and donated his money to charities but after he came out he was attacked. He used his telepathic powers to knock the men out. He served more time for fighting back. Your trying to serve justice but that's not it." Jean then said "I will fight this act till the day I die. I will offer my school as a sanctuary for fugitive mutants. You can send The avengers and mr . Stark after us. Now I ask you to leave my school ." 
David was surprised he never seen Jean do serious.
