I really like what you’ve done here. My one critique is with the “small-minded coward” bit. It doesn’t have the ring of truth that the rest of the piece has — maybe that’s because it doesn’t seem quite bad enough to inspire a time-travel trip to take it back. But all-in-all, very well done!

You’re absolutely right. I had a litany of insults, and of course no space for them. Next time I will edit.
