It seems to me that one could recall what those particular issues or matters were and then simply search to find them. I would think that discovering this "obvious bias" would have left quite an impression ... in fact, it seems that it did.
If the bias is so obvious it ought to be easy to provide examples ...
Instead, you are spending a significant amount of time and effort to defend your comments and avoid doing so ...
I'd say that in and of itself might be quite telling.
If there's one thing that earns my complete scorn and utter contempt, it is when someone - who, when they are called out - refuses then to address the substance of an issue and refuses defend and/or back up their positions ...
People who do the above and are arrogantly dismissive while doing so earn a special place in rlent ****
