I think the narrowback unibrow goblins in question always had a psycho-sexual crush on Mr Collins, hence their obsessive slagging-off of him.
(Ten or fifteen years earlier PC's answer would have been far more aggressive.)
Some other examples of their nastiness.
They wished AIDS on Blur at a pre-HAART time.
Blur would put the other cheek.
They called Michael Hutchence from InXS a finished man in public when it was well-known that he was in the middle of some serious psychological problems.
Shortly afterwards, he would commit suicide.
And more, more, more things...while they always get away with them.
There are also their anti-democratic, IRA and misogynistic tendencies.
Now they start insulting their own fans.
Whatever...
And no, they have not become less nasty as they get older.
The fact is that the biggest bastards are also the biggest arse-lickers of all toadies, apart from being the prickliest ones.
PS: They also envy PC for having two eyebrows while they have only one.
