Detest violent crime against men (5)
I believe the answer is:
abhor
'detest' is the definition.
(abhorring is a kind of detesting)
'violent crime against men' is the wordplay.
'violent crime' becomes 'abh' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'against' means one lot of letters go next to another.
'men' becomes 'OR' (military abbreviation for Other Ranks).
'abh'+'or'='ABHOR'
Can you help me to learn more?
(Other definitions for abhor that I've seen before include "Not like" , "Regard with disgust and hatred" , "can't stand" , "cannot stand" , "Abominate" .)
