Students often pick on tito, but he says that this is a sign that the other students like him. what defense mechanism is tito displaying?

Denial Mechanism 
Which is the refusal to accept reality or fact, acting as if a painful event, thought or feeling did not exist.

He is saying what he wants to think. Also ignoring the problem and showing kind manners that usually makes people mad when they pick on people I don't think he is really doing a defense mechanism but the kind manner thing is kinda a defense mechanism but he isn't really doing that at the exact moment. To me it seems like he is ignoring reality and just relying on what he wants to believe.

Yes violent video games can increase the risk of the person wanting to try out the things in reality , in real life . the person may be mad and want revenge and is playing the video game and the video may give more ideas of what to do sounds confusing but yes it does increase the influence sadly on violence out there . there is much evidence of many incidents where violence has happened sadly , like the columbine school shooting on april 20 of 1999 r.i.p to the innocent lives lost may they rest in peace ❤️also violent video games you can choose your choices on who to shoot and what to do and what to do not to get caught like gta 5 no hate on it i'm personally a big fan but you can choose to do bad or good on the game just like real life. people might illusion it in real life n try it out because in the video game it seems so realistic.
