Zoro trusting robin or not has never been a plot point in the series the only reason you bring that up is to distract from the fact that sanji just put her in life danger and also gave her exact location to literally every enemy in onigashima
asking Enel to hold back just because she's a woman LOL.... I'm speaking facts...
As for putting Robin at risk... you apparently so blind when you read the dialog, why?
1- Sanji's words were boardcasted... meaning, Robin herlself know that Sanji's words reached every ear
2- Sanji said "I was held as prisoner" so he already warned her that it's a trap
3- Robin was happy for asking her help, and trusted her despite both knowing it's a n obvious trap... if Robin is HAPPY for Sanji's request for help, you have no right to speak on behalf of Robin, you just need to stay silent and watch her kick ass... and do not speak words on behalf of her like she has no presence, or did you learn to disrespect Robin from Zoro?
