It's easy to spot a happy clapper by excessive use of phrases such as ..."grow a pair"..."entitled twats". In addition, there will be unnecessary and overuse of the "f" and "c' words, as if swearing adds some depth to their posts (it doesn't).
Invariably, they will also be extremely dismissive of other people's views.
Nobody minds a bit of positivity, in fact after our recent run it is extremely welcome but the "everything is fine because we were once in the old 3rd division" approach is pointless. Things have changed, the people behind our club will not accept being middle of the road and will not be resting on our past laurels.
