Tell me about it, I'm vegan/non-animal-product-using. It's not just the distant past that's "morally questionable" for me. So the problem you are fixing is that I haven't "accepted that social mores fluctuate over the generations"? And am "trying to erase" Feynman from the history books? Uh no. It sounds like you copied those bland clichés all out from your high school notes. I don't disagree with any one sentence, but put together, I wonder who benefits from hearing that speech. I'm no SJW or general hater of dead white males, don't worry. Maybe it's the standard reply to them. Sorry if this all sounds condescending - what you wrote comes over as super-condescending also. It's difficult when we have no idea who we're talking to!
