Huh, given that something like 15% of Americans are on SSRIs, I wonder how this affects the political landscape (which seems overrun with a new kind of moralizing in the last few decades)
There are secondary effects as well, for example, women have been shown to select for more dominant, aggressive men when fertile and meeker providers when not - how might that shape our social landscape, if a sizable proportion of women are kept permanently in a hormonally induced infertile state?

If scientists had a camera and microphone in every room on earth (which is of course impossible) they would learn a lot more about humans than they would with studies in artificial lab environments where they have to guess if the results have any applicability to real human behavior in real human environments.
Your second link lists only St. Anthony Family Practice Residency Program as an affiliation.
I can't say one way or the other whether your assertions are valid. But your choice of sources warrants caution.
There is something like Serotonin Irritation Syndrome which can cause aggressive feelings and thoughts. Personally I tried to increase my serotonin twice, once with Tryptophan a few years ago and recently with Inositol. Both times I felt very aggressive. Maybe I should use it right before a chess game, who knows it helps ;)
It is sometimes mentioned that for people who are sensitive to psychosis (like me) this can be a tipping point towards aggressive behaviour.
