hes got this unfortunate habit of reinterpreting what was said to him,
and arguing that rather than what was actually said.
ie
you didn't say "LN isnt more private than monero because most people dont use its privacy features"
saying most people *dont actually use it in a private way*
is different than
"it isn't private"
but understandably he doesn't want to own up to the shitty UX and hassle of using LN privately.
