You don't have to buy into it - christ, majority of the Blues on here aren't Scouse - but still, it's a valid question.
We hate the majority of these players every other weekend, so why should we get behind them just because they're from a few hours away from where we live? Nah.
Most of our traffic is Liverpool but get your point.
Also agree on the sincerity element - it can feel like its lacking integrity to suddenly support players you otherwise dont like but then that view can also be a bit small time.
I could never really get behind England when it had Gerrard, Carragher, Ferdinand and Capello as manager etc.
