Lol, I already apologized in that thread because I was misinformed/I misinterpreted. On the shoulder to shoulder subject, one is against an opponent and hence equality or relativity can be established. The other is in a group.
@HeroesNZ beautifully explained the shoulder to shoulder shit in another thread.
Sanjis strongest attack on his shoulder to shoulder crewmember gets only an ouch, that hurts with support of two other attacks. Unless you are suggesting that Sanji would say or react similarly to getting hit by a Bajrung Gun then this shoulder to shoulder does not imply the equality that people are suggesting.
