Crude enemy slur finally ignored — not in good taste (8)

I believe the answer is:
unseemly
'crude' is the definition.
(thesaurus)
'not in good taste' is the wordplay.
'not' becomes 'un' (prefix meaning 'not').
'in good taste' becomes 'seemly' (I've seen this before).
'un'+'seemly'='UNSEEMLY'
'enemy slur finally ignored' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for unseemly that I've seen before include "Not becoming or fitting" , "Not decorous or fitting" , "Indecent" , "Indecorous, unbecoming" , "Unbecoming, not fitting" .)
