There is no denial that the refs are not consistent or that Rangers have had some contentious VAR decisions.
You've failed to bring any substance to this thread or facts highlighting this supposed bias. I've given you have a dozen examples of different clubs highlighting different issues.
We got a penalty on Saturday that imo shouldn't have been given, but apparently the rules state it should. That's not referee bias, that's Collum applying the rules effectively. Just because you think he's wrong doesn't make you right.
I've asked you numerous times go show me examples of bias to allow for a debate. You can't/won't because it blows your theory out the water.
