When contemporary ninnies complain of toxic masculinity, they are not entirely off the mark, even if they remain oblivious of the implications.
Masculinity becomes toxic when the complexity and attendant fragility of a society grow to the point where the male libidinal drive becomes too disruptive to accommodate. Such tightly regimented, dense, automated, networked societies require subjects that must increasingly approximate to genderless automatons.
Freud had already observed in Civilization and Its Discontents that the level of interdependence and collaboration that social life demands would be impossible without the repression of aggression. This was always true, but modernity pushes the instrumentalization of the human organism to the point where the modern subject must be completely stripped of any inclination that might ever so slightly misalign it with the Borg-like corporate hive that encloses it. Inevitably, this translates into an aversion toward every manifestation of refractory masculinity.
The early modern worshipers of the machine did not foresee this. To Marinetti, the machine promised hypermasculinzation, an amplification of the most primitive virility. What it delivered instead was a wholesale gelding of Western man, his transformation into a species of hermaphroditic worm. And it is these invertebrates who today declare that masculinity is toxic, for to them the sight of a man can only convey an intolerable rebuke.
