What could be more patronising than suggesting anyone who disagrees with you is 'possibly responding to a 'herd mentality'.
Herd mentailty in Christmas songs? Give us a break. The person suggesting this is just as likely to be making the suggestion because everybody whose approval they seek doesn't like it and is doing exactly the same thing.
Also looking at the names posting on this thread, they are the names of people who nearly all have track records of never being afraid to put their heads above the parapet and disagree with any one and everybody where there are disagreements, so to suggest that they might succumb to the herd mentality over a Christmas song, of all trivialities is really the sign of someone on their back foot and flailing out wildly.
