The problem is that this list loses all of the nuance behind some of these ideas and spins them into being negatives, when inherently they are not necessarily bad. They're the answers you're going to get from people when you sit them down and ask for a response off the cuff, not responses you're going to get when you ask for more than a bullet point.
A classic example is "boys don't cry." Every well adjusted adult male knows this doesn't mean what it says on its face. Boys don't cry, as a concept, means that there are times and places for showing your emotions that are appropriate and inappropriate. Boys don't cry is about keeping in mind that your emotions have an impact on those around you who are relying on you and if you aren't careful with how and why you show them you can negatively impact others. No well adjusted adult male would actually sit down and think they actually have to bottle those emotions up no matter the situation.
It's better to be mad than sad is actually quite simple to me. Sadness is a terrible emotion for which there is no relief. Madness is an emotion you think you can do something about. In a lot of cases I feel like this is actually a net positive, giving the ability for a well-adjusted person to channel the emotion into a positive outcome. Madness is related to drive for a lot of guys. It ties in with "don't get mad-get even". The goal of mad isn't to just blindly take out your rage on others like it seems this may be presenting you should do. When I am sad about a situation and I have the option to turn that situation into a challenge I can be mad about, it gives me he drive to better my situation. So yeah, a lot of the time I'd rather be mad than sad. It's an emotion I can do something with, I can "get even" and by even I mean I can push myself to overcome whatever situation I've been put in.
It almost seems like all of these are positive aspects of masculinity spun to be negative aspects by making them negatively framed bullet points. I have personally never met any male who would even dream of taking those bullet points at face value, but they would probably all give you similar things if you asked them for bullet points. Trying to describe masculinity isn't something that's easy to do. It's like asking someone "who are you really?" and expecting them to give you more than "Well I think I am a good person." You're not going to get it without asking some real questions or delving deeper.
There are very real problems men face in this world, but on of the more recent problems is caused by the fact that the behavior of young men is now considered inappropriate in almost all settings. Boys don't behave like boys, boys misbehave. Education, which used to center around them, now considers them problem students, all the while focusing on making sure girls aren't alienated in classrooms.
Anyway, it sort of angers me that there was an arbitrary constraint on this thread that we can't discuss the negative impacts feminism may have had on the situation of men, whether intentional or unintentional. If you actually want an accurate picture of why men are the way they are I don't see why you would eliminate a huge section of society's input on what it means to be men in the modern context.
