It is perfectly reasonable to have a sense impending doom based on our form and remaining fixtures but such negative feelings must not be transferred to the players on match days.
We have a chance to stay up and until we don't, there is nothing to be gained and everything to be lost by a lack of support during games.

No it's not being realistic at all, as the OP said it's just negativity. FFS the fat lady hasn't even warmed up yet let alone start singing.

It's a good job that those of you that have given up weren't alive when Dunkirk happened as you will all have been down on the beaches waving the white flag. Sadly that never say die, never give up spirit is sadly lacking among most of the posters on this forum.
