Why wouldn't I heap blame on Musk (as well as on Trump, mind you)? The guy's deranged and repulsive.
I don't think your objections are fair. Let's go over them:
The average Trump voter doesn't know much about Epstein, and certainly doesn't believe Trump was involved in anything with that scandal. Any evidence that may turn up would be considered "fake news" to them. Whatever you may think of Trump voters, and whatever things they really are to blame for, knowingly voting for someone they believe to be a pedophile isn't one of their sins.
Musk just implied Trump is a pedophile (or is suppressing certain documents because of his links to a pedophile). Musk also claims without him Trump wouldn't have been elected. These are Musk's claims, so he has thrown away any possible defenses of "but I didn't know/believe this" and "but I'm irrelevant in the grand scheme of things".
You also claim Musk could defend himself with "but I didn't know at the time". This is very, very weak. When exactly do you suppose he learned this? In the few days that have elapsed since this very public falling out, maybe even a few days before? Oh, please. You know you don't believe this, these two were heaping praise on each other and calling themselves friends for most of their collaboration since Trump's second term, and only now Musk found out about Epstein? What, an aide rushed this info to him just in time for their current breakup? Absurd.
Any way you slice it, Musk had this accusation up his sleeve the whole time, he just chose to deploy it now.
So again I must ask, what does this say -- in his fans' eyes -- about Musk as a person?
PS: You seem to believe I'm somehow defending Trump here. If that's your worry, let me be clear that I think Trump is a disgrace. I don't know whether he's a pedophile though, unlike Musk I don't claim to have seen any secret documents. To be honest I wouldn't be surprised if both Trump and Musk are pedophiles, these aren't exactly examples of decent human beings.
PPS: it has also just occurred to me you could be wondering why I'm focusing on the outrageous things Musk has said, but not on the contradictory, absurd or just plain dumb things Trump is saying about Musk? Well, because Trump has an expiration date. I suppose he can do lots of immediate damage to Musk, but he must do so now. Musk, as the world's richest person, has a much longer shelf life and more time to do damage to the US and the rest of the world, and bizarrely, has a large cult following. So I wonder what his followers think.
