Emma Gonzalez the LGBTQ activist who wore a Fidel Castro Jacket and a Communist Cuba flag patch on her right arm the day of the protest, said that she and her friends KNEW that Nikolas Cruz was "weird" and they purposefully ostracized him starting in middle school.
"Ostracized" him is another way of saying they started BULLYING him in middle school.
Yes, the "Parkland survivors" are all bullies.
She said that since he became a murderer, he deserved all the bullying he got. Again, this just shows that these people are emotional about it.
