Forest found themselves a goal and a man down midway through the first half after Tommy Smith fired Rangers ahead and Majewski was sent off for his crude 23rd-minute lunge lunge on Adel Taarabt.
But they hauled themselves level through David McGoldrick's fortuitous strike and defended heroically as the npower Championship leaders cranked up the pressure after the break.
Warnock said: "Let's be fair, I wish we had referees like that every week. It's always difficult against 10 men but our strikers could have done more.
"To concede a goal like that is Sunday league stuff and the equaliser summed it up, how lucky can you be?
"If we'd have been tight for that period they would have had to come out rather than park the bus. But these are good points. The game won't decide our fate, the 15 we have left will."
