I actually greatly appreciate that, sensible explanations beat childish name calling any day

Read both those concerns, one requiring the 51% control of mining already has known potential exploits even in bitcoin so, although legitimate, comes with the territory to some extent.
The incredibly anachronistic fractional reserve analogy is intriguing, but it's not totally apt, since in this LN exploit it would require active intent to defraud (not that someone wouldn't given the opportunity).
The segwit as softfork issues I see as more concerning, less the irreversibility but more the potential chain breakdowns. Immutability is the cornerstone of this whole technology. With that said it's far from impossible to imagine, with active code development, the kludges being ameliorated or even eliminated over time.
I'm no fan of fractional reserve banking, but see much of this concern hinged on some EXTREME "what ifs", and even then if the tech fails and LTC goes with it, then it will serve as a lesson for BCC and other teams to learn from.
Segwit isn't sexy, or even remotely pretty, but it does seek to address long term usage issues in existing blockchain systems. Ther MIGHT be better solutions, but it seems insane to not try it. I have some money in LTC and am OK gambling that on code that might help all of us, even if that help is only learning the hard way it doesn't work.
