they can't, that's why we should ignore them. they are just ignorant speaking of things they know nothing about.

calling it 'a scam' i mean... junk email from nigerian princes is a scam.
advance fee Nigerian-inheritances are... a scam.
'investment schemes' on telegram or from random text messages... ya those are scams.

but i have a home miner, it heats my living room i receive payouts to my LN Address... which i use to post here stack sats + play lightning blackjack.

if they've never heard of lightning or a 'bitcoin node' how can give a fair assessment of bitcoin?

Exactly... they are all speaking from a place of ignorance.  If they really understood Bitcoin, it would be okay to be skeptical, but you're more likely to say something along the lines of, "I just don't think it'll work," rather than all the strawman attacks about it being a scam.
