Not really because isn't it Patriarchy that put them in danger in the first place?
Why weren't there enough life boats? Why weren't they lowered sooner? Why wasn't a distress call sent out sooner? Why were they basically racing across the ocean in those conditions against the clock to impress by getting in early? Does anyone believe that the elite women and children would have faired as well if the poor women and children hadn't been locked bow deck alongside their men? Why were the life boats filled to capacity? They had time; why didn't they make rafts (there was lots that could have been done to save more lives).
All of those things can be tracked back to Patriarchal conditioning and Patriarchal thinking.
So where's the irony? That in one unusual instance Patriarchy "benefitted" women over men, but only elite women so it didn't really benefit women, it benefitted wealth (some of whom were women).
Or that the Patriarchal version of dominance hierarchy creates the conditions that makes the lives of most people strained and stressed or difficult and dangerous and then demands gratitude for the crumbs it drops or the few times the underlings fare better?
