I see. I won't deny that there are some Monero users that use it for signaling. Agree that normies don't care either.
Also agree with you it's indisputable that Bitcoin itself is used more, but not completely convinced that Lightning is used more than Monero especially in a private way (not disproportionately using custodians like WoS that can basically see everything their users are doing)
I think there are areas that Lightning clearly excels in when it comes to privacy (i.e. better counter-party privacy + no public fees + no public blockchain) and areas Monero does (i.e. better tx amount privacy from third parties - nodes don't even see partial amounts, besides mining fees of course)
