Women's value being reduced to only the sexual appeal of their bodies is both prevalent and crappy. Obviously the same is true for all people but even though male models, actors, and superheroes are as anatomically unlikely as female ones the social pressure on masculine folks is not the same. I tend to cheer for anyone who is happy to speak out about that problem but sometimes I have to take issue with the way they do so. The trick is that there are two entirely separate things going on when people take issue with other people's appearance and people often conflate them.
Sexual attraction is something that is essentially random and mostly beyond conscious control. I like feminine bodies and I don't get to choose otherwise. Some people like tall folks, some like brains, some care about income, and some are really only interested if you are five meters tall and constantly puke up purple giraffes. Trying to tell someone to be sexually attracted to something they are not is both nearly impossible and unethical. The only thing we can do is accept that people are sexually attracted to all kinds of things and there is nothing we can or should do to try to convince them otherwise.
The problem comes in when people confuse sexual attraction with worthiness. That is, if they aren't sexually attracted to a person they blame the object rather than the viewer. Attributing moral inferiority to someone on the basis of a lack of sexual attraction, deeming them unworthy, is something we can train ourselves not to do and something we must strive to eliminate. The most common example I think is fat shaming - there is nothing wrong with being sexually attracted to slim people but it is deeply awful to shame people for being fat. Nobody owes it to you to be sexually attractive to you in particular.
One corollary to this is that nobody owes it to you to be sexually attracted to you. I have seen lots of people trying to push slogans like "Everyone is beautiful!" and I really think they should be saying "We are all worthy of respect regardless of sexual attraction." If everyone is beautiful and nobody is ugly than we might as well never use those words to refer to people as they are meaningless. Beauty is in the eye of the beholder. Everyone is beautiful to somebody, some people are beautiful to most people, and everyone is ugly to somebody. Others are absolutely entitled to think you are ugly but they shouldn't find you unworthy on that basis. It is important to examine our own sexual attractions though to see if they are coming from deeply rooted racism, sizeism, ableism, etc. and to not use "Sorry, not attracted" as an excuse for bigotry.
I saw a Buzzfeed video featuring a guy singing about how dividing the world into tit men and ass men is terrible and waxing romantic about how he loves a girl that reads. Thing is I share his particular preferences - I like feminine bodies and a partner who is smart, well read, a dangerous debater, and deadly clever can easily amplify that initial lust or even create it when it had not otherwise existed. But positioning sexual attraction to women who are reading a book as morally superior to sexual attraction to breasts isn't helping anything. People who aren't smart and aren't good debaters get tossed on the heap and we are left still in the same boat where people are deemed unworthy, just for different reasons. That the singer has selected a series of physical traits he cares about but slags others for selecting a particular subset of those traits to care about is a bit of hypocritical heteronormativity I doubt a lot of people notice.
The solution is not to say "Well *this* is the trait everyone should be going for" because that just leads to marginalization of a different set of people. We also can't pretend the problem away by claiming that everyone is sexually attractive to an open mind. They aren't. The solution is to say that you can be sexually attracted to anything without reproach but that you should treat people who aren't sexually attractive to you well. You don't have to love them, have sex with them, or even like them but you do have to accept them. Someone out there wants them and the fact that you don't is your problem, not theirs.
Note that attraction comes in many types and that sexual attraction is regularly privileged over the other types. This is especially problematic for those on the asexual spectrum but it creates problems for many other groups, notably women. My central message here applies equally well to other types of attraction - treating people badly because you aren't inclined to be close with them and positioning it as due a moral failing of theirs is terrible too. I do think that this issue is far more prevalent and egregious when it comes to sexual attraction though so that was my primary focus.
