I'm sorry but that's a silly comparison. One happens to be a victim of what she's disgusted at while the other is homophobia.
It matters because she was a victim of breast cancer. Should we never care what rape victims think if they're offended by something representing rape inappropriately?
As for why she was disgusted, she thinks the focus on saving boobies is wrong and offensive. Who gives a shit about saving boobs? It's the lives that matter.
It wasn't really a "comparison." It was more an example to show that just because someone finds something offensive doesn't really mean anything in and of itself. One's reasons behind those feelings are more important.
But I'm not sure the focus was on saving boobies. Or at least, I think they intended "boobies" to be a stand-in for the women who have them. And they assumed that people were intelligent enough to understand that. We refer to people by their characteristics all the time. "Those redheads over there" or "Who are the suits?" or "Check out Mr. Muscles" or any other number of examples. Saving "boobies" is just a tongue-in-cheek metaphor. Granted, I'm sure there's a bit of a literal element to it in that these guys also want to save actual breasts because they enjoy them, but I think it's clear they're talking about saving people's lives as well. It's not an either/or proposition.
Because they're making it all about breasts while also getting something out of it. It's not a matter of being consensual because the women they're doing this to could have had a multitude of reasons for agreeing. Maybe they didn't care or they felt pressured to do it for breast cancer or maybe they thought they would be called prudes. People are assuming all of these women did it happily with no problems.
I'm still not understanding why them getting something out of the deal is a bad thing. Again, it might not be the optimally good thing, but how is it bad?
And, sure, the women could have a multitude of reasons for agreeing. But outside of coercion through violence or something like that, I'm not sure why that matters. If I offered you $5 to give me a high five, you might only acquiesce because you don't want to seem uptight or you might really need the money or you might just really like high fives. Who knows? But I will treat you as a mature adult who is capable of handling such a decision. Just like here, I assume those women are competent and capable enough to make that decision for themselves. Just like I'd assume men would be competent and capable enough to make such a decision.
Yes, they might have felt pressure. But that's true of so many decisions that people make daily ("Should I go out with this guy even though my parents disapprove of him?", "What should I wear today at the interview to make the best impression?", "Everyone else is taking shots, should I have one?"). You wouldn't ask the same questions about those decisions. Why is this one any different?
I think you do a disservice to women when you treat them as children incapable of choosing things on their own. Even if social pressure is involved. News flash: women are sometimes capable of standing up to social pressure. And I'm sure there were a lot who did and were left out of the video.
