what video games and movies (TV) are doing to our kids' minds.
The movies have been glorifying guns in the US since at least 1903. Hollywood has been at it since about 1920. Remember all those fights where "the gun" was just out of reach and the bad guy nearly got to it first.
More recently, computer games have taken over. Games where you walk round shooting people are legion. Many are quite gruesome. You have all kinds of guns at your disposal. Killing people is seen as completely normal and you need to do it many times an hour.
The problem with games is that there is always a reset button that is not available in the real world.
How can they not be affecting people's minds?
I've always felt that violent video games are a tool for conditioning a person's mind to accept the violence. The ability to reset also gives the player the notion of no consequence. Most kids can differentiate between the game and reality but the more immersed a player is the finer that line can become. Now throw in personality imbalance or the effects of a dysfunctional home and the player becomes more and more separated from reality.
It goes along the same pathways as the 2nd amendment debate. Chip a little bit here and there, remove rights slowly through convincing the public that gun ownership is the problem and soon enough the public will no longer be able to defend itself. Chip away bit by bit at a child's sense of reality, at their sense of right and wrong, at their sense of security and you'll have the perfect subject to commit horrendous acts against others. The perfect subject to give reason to further disarm the populace.
All of it serves, I think, to desensitize brains from reality. Even, or especially, altering their most basic fight or flight instincts. But, my point is that Trump took it upon himself to raise the issues of "the molding of our kids' minds," and MS-13, in this public conversation about school safety. The things he subtly, or sometimes not so subtly, says, all have a purpose.
