Mass shooters have been linked to anti-psychotics and antidepressants.
We're pumping people with drugs instead of curing them.
Of course the liberals want to ban guns instead of curing depression.
I'm not an evolutionary biologist or anything, but there's some very important things that evolution taught me. NOTHING exists for no good reason, depression included.
It's been studied that animals can get depressed and will self-mutilate or cause harm to their self, not consciously knowing it will cause them death, but they do it because it's instinct.
You take a dog from its family, it will whine, stop eating, become aggressive, lethargic, depressed, and die sooner.
If you kill a member of a chimp society, our closest cousins on Earth, they will mourn it, and some will get depressed. Depression is a mechanism that prevents the socially inept from breeding.
Depression is loss of person...
Chemically, some people might be more genetically prone to experience the effects of loss than others, so there's a genetic component as well.
But this "Loss of person" can occur even without losing them physically. A kid may become bullied too much; and in a way, he loses person, because he's ostracized by society. Studies show, depression rates don't decrease in schools with anti-bullying programs; the ostracization is still there. The loss of person is still there.
Liberals live in a depersonalized world; and they maintain it with materials, substances, and good feels, self love, fat acceptance, gay acceptance, etc. They're trying to pretend that they're not alone, but they take anti-depressants left and right.
