Fair enuff 🫂
I mean I think most Sanji fans have a similar view on their dynamic as you do (I do at least), know a few that genuinely think they are equal but I think they are in the minority tbh. Regardless, can't speak for others so will stop here
Completely disagree with your take on PoL though and I think you're making way too many assumptions.
It's not like Sanji fans invented PoL out of thin air. This is an ability that Oda had Sanji display not once but twice on Egghead and was also hinted at as being the true ability of the buccaneers. This ability quite literally destroyed Kizaru's lazer, something that completely defies the laws of physics which Kizaru commented on by the way and allowed Kuma overcome his programming so not sure what the problem is with Sanji fans getting excited about it. Saying it's cope is a bit too pompous/condensending imo, again I get it you don't acknowledge PoL as a legit powerup hence why you think it's cope but don't really get why you can say that so confidently as 1.) for the reasons I already gave above 2.) Sanji's development post-ts has been pretty unqiue so is Oda going a different route than ACoC with at this point that much of a stretch?
Also on ACoC again, I'm gonna have to disagree with you again. You can think ACoC is a great powerup without considering it the holy grail. I've made this point several times already, Kaido might say Haki supersedes all abilities and that ACoC is the bee's knees but Blackbeard will tell you it's devil fruits. It's all just subjective at the end of the day and how far you can take an ability is ultimately dependent on the individual imo. So there's nothing wrong with Sanji fans or Law fans not conceding to the whole ACoC rhetoric.
Back to PoL, on one hand you're conceding that Oda's adding new shit to the series in the form grimores/magic and stuff but for some reason PoL which is relatively new (if we ignore Garp's fist of love) is a no go bcoz Oda added new shit to series? I don't get it.
Lastly with regards to PoL and immortals, given what that ability can do I wouldn't be at all surprised if it can indeed hurt immortals.
The ability quite literally contradicts "reason/logic" be it Kuma overcoming his programming or Sanji's feats on Egghead.
