That's quite a creative definition of positive.

So a man “illogically and hysterically” punching a wall because he had a bad day is positive because it's biological?

in that case what is the central idea being pointed at by the misnomer 'toxic masculinity' ? interesting to consider that prevailing framing as being an inherent critique of masculinity as a whole. personally I dislike the phrase 'toxic positivity' for similar reasons, it's like saying that a turd may be made palatable.
