Any comments on this?

Just Luke doing Luke. One more insane rant. What with the earth at the center of the universe, prepare for a PoW change, kill all the non-xtians, and the like.
One of crypto's more ... umm ...
colourful characters, to be sure.
FWIW, Gregory Maxwell also believed that satoshi's design was fundamentally and irredeemably broken. And these are the 'geniuses' that so much of the community choose to follow.

You highlighted one of the key differences between bcashers and bitcoiners. Bcashers follow people. Bitcoiners follow ideas.
Moving on, then. Luke's a bit nutty, but he's done more for Bitcoin than anyone involved in Bcash:
- Created one of the very first mining pools in 2011, and in 2014 released BFG miner, open source freeware to help others operate their Bitcoin miners. Both initiatives contributed significantly to helping Bitcoin stay decentralized.
- On March 11, 2013, Luke was the first to warn others that the Bitcoin blockchain was splitting and to call for emergency measures.
- Despite his interest in mining, Luke has always supported individual Bitcoin users, as was illustrated by his work on User Activated Soft Forks to help support SegWit activation.
- With 321 commits to Bitcoin core, hes currently ranked by github as 7th most prolific core dev.
- Even though hes most known for extensive code review and testing, Luke has contributed significant improvements to Bitcoin, such as figuring out how to deploy SegWit as a soft fork and BIPs 22 & 23.
