You'll often hear in the "manosphere" that testosterone is this wonder drug which makes you an "alpha", cures depression, and so on. This is bullshit; at most, the difference is that with low testosterone, you'll have the kind of depression where you're crying a lot, and with high testosterone, you'll be staring at the ceiling instead.
>Does it really cause aggression?>Is this feminist propaganda to make it seem males are predisposed toward violence?It's absolutely true that testosterone is connected with violence, but it doesn't make you violent directly. Instead, it increases your risk tolerance and makes you more willing to sacrifice things in pursuit of social status for you and your group. This means that depending on the environment, high testosterone can manifest as everything from violence, through entrepreneurship, to self-sacrificial altruism. The deadly mixture for violence is high testosterone, low IQ, and a social environment with few opportunities for legitimate advancement.
The best response to feminists who try to paint men as evil because they commit more crime than women is to point out that this is part of a general pattern where men do more of everything. The majority of history's horrible criminals are male, but the majority of the greatest innovators, humanist philosophers, and peace negotiators are also male.
