Why does it offend people so much that someone would be looking out for you? I don't mind. My all-time favorite dive buddy terms himself a chauvinist -- I suspect if we ever got into his actual opinions about what women are and what they should do, we'd end up in an argument. He has never, ever suggested I'm incapable of doing any dive we have planned together (in fact, on occasion, he has egged me on when I'm being cautious) but I know for darned sure he watches to make sure I don't fall on steep slopes, and he'll step in and offer to manage equipment if I look like I'm not doing well. My guess is the same attitude extends underwater, which means an attentive buddy. As long as he doesn't step on my toes about what I would like the two of us to do, does it matter? If anything, it makes my dive more pleasant and arguably safer.
If somebody decided to make a practice of watching out for divers in blue wetsuits, would there be this much fuss? "Watching out for" doesn't translate into "looking down upon" or "preventing from doing", at least not in my book.
