With all due respect, I don't buy the "Bullying" excuse. When the Left talks about bullying, they are using the term in an Orwellian fashion. They usually use the word to describe Christians and others who disapprove of homosexuality. Disapproval = Bullying. It's nonsense. It isn't bullying.
"Large schools" doesn't fly either. I graduated from HS in the mid-60's. We had 2,000 students in three grades. No such problems. And like others, we had a shooting team, who never shot anyone. We had students from blue-collar families and students from white-collar families. All of the students were white, and we had a dress-code.
The dress-code is important. I'm not aware that any of these school schootings have ocurred in schools where uniforms or uniformity are required. This ties in with "Bullying". Today, students seem to be allowed to dress in any manner, including clothing and hairstyles that invite ridicule from other students. Many of these shooters appear to have intentionally adopted an appearance that led to ridicule; ie - bullying.
Certainly, the Psychotropic Drugs are a huge contributor, and the rationale behind the Rx meds is diagnosing boys with made-up ailments that simply amount to boys acting like boisterous boys, rather than acting like passive girls. Ironically, giving depressed people anti-depressants makes them depressed, And homicidally-aggressive. Yeah, that seems to be working well.
The shooters are almost exclusively Democrats or the children of Democrats. Remember, "Liberalism is a mental disorder" isn't just a catchy saying.
So... crazy Democrats on drugs, who often chose to make themselves look like weirdos, so they could be ridiculed or "bullied" They usually used firearms that didn't belong to them, and if they did own the gun, they never should have been able to pass a background check. But they did pass because somebody didn't do their job in reporting disqualifying information.
And the schools. And the local "Law Enforcement". These two might even be the larger part of the problem. In a previous career, I went into ghetto schools on the South side of Chicago, during school hours. Some of these schools were located in the middle of notorious housing projects, where various gangs squared off against each other constantly. There were never any shootings INSIDE these schools, although local gang-bangers really would have liked to get in and take out some rivals. The schools weren't pretty because the doors were covered with thick opaque material, were alarmed, covered by security cameras, and only opened from the inside. In other words, unless you went in the front door, you weren't getting in. And the front door looked like the other doors, but one of them opened from the outside. Upon opening the door you were looking at a bunch of armed, scary-looking dudes in uniforms, who immediately wanted to know who you were and why you were there. Visitors AND students. You had to go through metal detectors, xray scanners for your belongings, hand wands for anything that set off the metal detectors, and of course, you had to get past the very-suspicious scary-looking dudes. Suburban school boards don't want their schools to look like this, but it works. Open, gun-free zones don't work. And policies that prevent reporting of criminal behaviour to law-enforcement is suicidal.
Law-Enforcement. Maybe they should go back to being "Cops" and act like it. The reported deficiencies in this arena are simply mind-boggling. PC rules and CYA procedures are dangerous. Today's LEO's want all the bad-ass looking military style clothing and equipment, but they don't seem to want to adopt a military-style attitude of "running toward the sound of the guns". Maybe hire a different kind of person? Clearly, this is a huge part of the problem, and probably the hardest to fix. Voters need to elect better people to be Police Chiefs and Sheriffs. Other than that, pray.
Last point. Are these shooting being manipulated to happen? It's to the point where you don't have to be a paranoid cynic to wonder. It could be, but it is more likely that Liberal policies have created a "Perfect Storm" where these shootings are totally predictable. Ask yourself the horrible question, "Who, if anyone, benefits from these shootings?" The answer is, "The Totalitarians who want to bring America down." IOW; all enemies, foreign and domestic. Domestic = Democrats and other Marxists.
