So the true lesson of this post is that we should get rid of all the aggressive alpha males in our society. I guess I always found the idea obvious, but now that it has been validated, can we please start devising some plan for implementing it?

Sod off! Overt aggression is a pleasant relief compared to the subtle, catty 'niceness' that the most competitive humans excel at. Only get rid of aggressive alpha males who act out violently (ie. those without sufficient restraint to abide by laws.)
