You continue to ignore two things:
1. The vast majority of historians agree that Badr, Uhud, The Trench, etc. happened.
On the contrary, I've addressed them ad nauseam.
You just watched a video of two mainstream scholars noting that lots, if not almost all, of these details are made up. Most scholars don't take explicit positions on every event anyway, they hold general attitudes towards the sources and what they can be used for. They don;t look ata timeline and go "happened, didn't happen, didn't happen, happened, happened, etc."
In general though, most modern Western scholars reject the Islamic sources as accurate records of history with positions ranging from 'they are probably broadly correct, although with numerous hagiographical and legendary embellishments" to "Beyond a few basic details, they are almost entirely fictional and cannot be relied on."
Your position is that texts that contain obviously fantastical elements, and very clearly serve obvious theological purposes are nonetheless highly accurate in every detail other than their flying donkeys, angels and moon-splitting.
No modern, non-Muslim scholar takes such a position.
You simply assume scholars agree with you as you haven't read any. Harvard Professor Patricia Crone:
The problem is the very mode of origin of the tradition, not some minor distortions subsequently introduced . . .The entire tradition is tendentious, its aim being the elaboration of an Arabian Heilsgeschichte [salvation history], and this tendentiousness has shaped the facts as we have them, not merely added some partisan statements that we can deduct.
2. Whether or not they did is moot because Muslims believe it all happened.
It really shouldn't be so hard for you to understand your fallacious logic here - you are not addressing what Muslims believe, but assuming the historical details about what Muslims believe are correct, but inserting an evil Muhammad into this narrative.
If you want to address Islamic theology and what Muslims believe (rather than factual history) then you need to do it accurately and in good faith, not by cherry picking what is convenient and rejecting that which is not.
Muslims believe Muhammad acted in self-defence against those who sought to oppress or kill the virtuous Muslims. You think everyone was just trying to live in harmony until megalomaniac charlatan Muhammad oppressed everyone who didn't accept his prophethood. You are not addressing what Muslims actually beleive, so can't use that as a defence for why you can uncritically dismiss secular historical scholarship out of hand.
Your view recasts theology in terms of secular history, in which case the events actually need to have happened before it has any value. Otherwise you are writing fan fiction in a mythical Islamic storyworld.
Trying to explain what an evil, historical Muhammad (not the Islamic Muhammad) did in Situation X makes zero sense if Situation X never actually happened outside of a confected Islamic theological narrative.
