I didn't lump anything under anything, I was responding to Purkake. He brought up "government go away."
Video games aren't about the free speech of children, they're not the children expressing anything. And the right to protect children from speech can only be exercised in very limited cases. There's actually not a lot of legal precedent for prohibiting children's exposure to violent media. Sex, yes. Profanity, yes. Hate speech, yes. Violence, nope.
And these cases almost always focus on violence.
