'self-contradictory' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'against hollow man and tory cavorting?' is the wordplay.
'against' is a charade indicator (letters next to each other).
'hollow' becomes 'con' (I am not sure about this - if you are sure you should believe this answer much more).
'man' becomes 'm'.
'and' becomes 'n' (common abbreviation for 'and').
'cavorting?' indicates anagramming the letters (I've seen 'cavort' mean this).
'm'+'n'+'tory'='mntory'
'mntory' anagrammed gives 'tronym'.
'con' put next to 'tronym' is 'CONTRONYM'.

'that's' is the link.
