Abbot actually cut the budget for mental health assistance in Texas just last year, he took something like 200 million dollars away from it, now he's saying to call for the (now much reduced) help.
It's depressing and predictable that this happens time and time again, and the representatives of the NRA in office basically blame litterally everything other than their refusal to even just make it slightly harder for someone to get a gun.
I was watching a clip of a "secret buyer" type test where a program sent a 13 year old (with his mothers permission) in to try and buy various things, the scratch card seller, alcohol retailer, and tobacconist all basically had the response "lol, how old are you, no", the guy at a gun show "yeah this .22 rifle will do well for you, it shoots good". Admittedly a .22 rifle isn't much of a gun, but it shows how stupid the laws are that basically you're too young to drink, smoke, gamble, or drive but a gun at a gun show is fine.
None of the latter you mentioned are constitutional rights like firearms are, you're trying to equate firearms to a beer but they aren't the same thing. People in Ukraine are fighting Russia with firearms, civilians have taken up arms over there as if to prove the point and are successfully resisting an attempt to force a tyrannical government on them and remove their democratic rights.
