I think where this falls down is in that in order for it to hold, it has to make the claim that hatred and enjoyment both deserve equal legitimacy as something to personally identify with, and therefore have others express empathy for, as it pertains to leisure activities.
I think if you asked most people "if someone were to make active hatred (meaning its expressed in the form of activism or protest) of a leisure activity a tangible part of their identity, (a) is that healthy and (b) is it worthy of deference"...my guess is most people would say "absolutely not" to both (a) and (b).
Now if you subbed "enjoyment" for "active hatred", my guess is people would overwhelmingly say "yes" to both (a) and (b).
