Anfield, St James, and Selhurst? I've been to those grounds and seen fans leaving early. Unbelievable that a Brighton fan should say that Palace fans are better.
Stop running your own fans down.
I don't blame people with kids wanting to leave early. The game was rubbish, but more than that, they were probably already wet with the rain.
Who wants to queue for over half an hour for trains and buses in the pouring rain?
Live and let live. You support in your way, let them support in theirs.
