Onyedinma was sent off just minutes after putting Rotherham two up early in the second half and the decision to award two yellow cards in as many minutes from referee Bobby Madley angered the home crowd and baffled Taylor.
The decision turned the tide of the game and left the Millers having to hang on deep into added time.
Sammie Szmodics had an eventful game as he missed a first-half penalty and was at fault for Rotherham's opener, scored by Hakeem Odofin, before his second half double secured a point.
Taylor said: "The first yellow is my biggest frustration. We go 2-0 up, it's Fred's first goal and there is emotion. He gets pushed into the crowd by his teammates celebrating.
"Football is going in a strange direction. I know they are trying to make it a better product, but I would argue that it isn't right now.
