The topic is more narrow than just violence, it is about mass shootings. And if you look closely enough, you will see some common traits with the types of people that commit mass shootings. It is worth studying.
Studying? Yes.
Spreading insinuations around in public, before any such study is concluded? Not so much.
That's an old and well worn evil.
You should refrain from it.
The most common trait of people who commit mass shootings is that they are the victims of bullying. Bullying includes (though it is certainly not limited to) the making of public insinuations, without hard evidence, that certain types of people have undesirable traits.
You are a part of the problem, and your pretence to be a part of the solution isn't fooling anyone here.
