I mean, i praised Zoro for such actions on the roof even when they were not targeted at Sanji.
Right now we have specific focus on Sanji going out of his way to protect Zoro and help him, all while quite a lot of this forum's Zoro fans are shit talking Sanji to no end.
Be sure that i will call out Sanji fans if the roles reverse and they act in the same manner, but right now i'm talking about what we can see happening in this scenario.
But hey, deflect on "they do it/would do it to" to defend this behavior if you think that's the best course of action when such behavior get's called out
