David, you asked "what if it can be proven that massive non compliance to rules and cheating went on to give Biden the victory?"
David I don't know, as Christians, we have to be careful and listen to the Spirit, not man. We are in deep, deep, waters today, some are frustrated, and confused. David, for me personally "right now" I fighting this good fight in Prayer, and of course Prayer is the most we can do. I do believe the evil one is doing all he can, to work through some of our politicians and the MSM. I personally don't have any inside information on the truth of the results of the election, but God does.
The Good Fight, well to me this would mean, we need to pray about all this first, and if God leads us personally to stand up to this evil, we need to do so. There are many ways to stand up, not just physically, if us believers have personally heard from God about all this, he will lead us individually, that could work out to bring the masses together, to let our voices be known. We are called to speak the truth, and the truth is, this is not right, in my opinion. Brother David, I wished I had a solid answer, but for now for me personally, I'm going to wait on the Lord in Prayer, he will act, none of this has taken him by surprise, and I also truly believe none of this has taken our President by surprise.
It's really important now, as Christians, we don't just jump on any boats together, even if we see many others on those boats. More than ever, it's important we listen to God speak to us personally, because if you jump on one of those boats, God may have had a different calling for you at this time. As always, follow God, not man. Praise Jesus!
