The transgendered kids thing is rapidly declining in popular opinion. Pretty soon it's going to be one of those "what the hell were they thinking" moments in history.
The legislature are a bunch of cowards and have caved time and again to public pressure. It's not their opinions we to be concerned about, but the firestorm of backlash they are beginning to see on the horizon.
If a law encourages kids to engage in risky behavior that doubles their suicide rate, then that throws the whole "keep kids safe" argument right out the window.
You're looking at it from a point of common sense and logic. The state legislature has clearly demonstrated it doesn't operate on logic or common sense, instead operating by their own rules and focusing on their own political priorities instead of the priorities of the people and the responsibilities and limitations of their office.
Correlating firearms to what is largely mental illness will not highlight mental illness, but rather incentivize their priorities towards disarming the populace. They could care less about safety or helping their constituents unless it's suits their needs and goals.
I'm sure by now you'd have noticed that instead of cracking down on crime and holding criminals accountable, while at the same time addressing the culture that promotes criminal behavior and activity (i.e. what's happening in the Westside), they placed the emphasis on firearms. Why would this issue be any different?
