I have only rarely used the term - but tell me what term would you prefer to use for those who were against his hiring right fron the beginning, urged JL's departure all along, cheered his exit, and who still often turn discussions into JL-bashing - still blaming current problems on someone who's been gone nearly two years?
This is a reason for the constant back and forth arguing/bickering. Why do you feel you need a label or term for those who disagree with your opinion. You state your opinions and others state theirs. Nobody needs to "termed" or labeled anything because of how they feel.
