No the reason he asked that question about gang violence is because gang violence numbers are a huge percentage of mass shooting numbers, so if you take them out of the calculation then the percentage of trans shooters is much higher and it is a debate about trans shooters. On the other hand, if you include those numbers then it is a debate about guns in general and ideologies or mental health issues get lost in the noise. I would guess he mostly wanted to make a point that the definition of mass shooting is not really in line with how people think of them.
He certainly wasn’t trying to reach a shared truth. He was trying to win the argument. Which is usually the point of debate. But it would be nice if the goal was to reach a shared truth…
