Many (or most) of these "transgender" lunatics are already literally
suicidal anyway. So it's not going to be much of a "leap" for them to lash out like this and go on a rampage -- because they don't really care if they die. Just going on the fact that they are "transgender" tells you all you need to know that these people are, by definition, insane and completely out of touch with reality.
And they are brainwashed and true believers in the Leftist agenda that teaches them that it's ok to murder unborn children out of convenience, and that "there is no God" (and no moral absolutes), and that we are not a special creation, but are all just "insignificant accidents" that "evolved from the primordial soup due to random chance on a rock flying through space after a Big Bang explosion".
The problem here is not guns. Guns are just a tool. Good guys with guns are what deter and stop homicidal maniacs like this. An armed citizenry is actually the
solution to crime. The areas of the country with the most "gun control" (ie, Democrat-controlled big cities, Chicago, DC, Baltimore, etc) are the areas with the worst crime, because passing laws to ban guns only results in the law-abiding, decent citizens being disarmed -- while the criminal element in society continues to be armed...which results in those cities effectively being "gun free zones" (like schools) where the decent citizens are sitting ducks for criminals.
The problem here is a sick, disgusting, perverted, wicked society and culture -- ie, communist Leftist ideology that fosters wickedness and insanity.
If you truly want to "protect the children" at schools, then abolish these gun free zones, and allow teachers and principals to be armed....in addition to armed police officers or security guards at the schools. And then potential criminals will know that there is at least a decent chance that they will face armed resistance if they try to attack a school, which will largely deter them from even attempting things like this, and these incidents of school shootings will become much much more rare.
