Kyle has been remarkably clear-spoken and level-headed for a teenager throughout the entire thing. I'm inclined to give him the benefit of the doubt, myself.
I'm actually pretty impressed with him. Other than the one twitter incident, I think he's carried himself pretty well.
One other thing I'd like to add on the subject, as impressed as I am with this kid, I don't want to put him on a pedestal like the left has done with the anti-gun kids. They all have a hell of a lot to learn about life before anyone should think about relinquishing the future to them. The Leftists act like they're ready to hand over Congress to them, presumably because they're parroting the right lines.
But Kashuv has shown more maturity, and appears to have a more reasoned head on his shoulders than Hogg, and the rest of the anti-gun students. Plus, I don't get the feeling that Kashuv is exploiting his new found notoriety in the same self-centered way that Hogg is. Kashuv has challenged Hogg on twitter to debate him, but of course that hasn't happened. I think if they did debate, it would most likely look like Kashuv talking about statistics and facts, and Hogg making emotional appeals and insults and claiming Kushuv has the blood of all his classmates on his hands.
