Listen, I agree with you. I also encourage body autonomy. What I'm trying to point out is that there are different expectations from society for men and women. Unfortunately, democracy (or the quasi-democratic pretend version that we have), is largely dependent upon a consensus. Right now, the consensus says, there are different expectations for men and women.

Let's take this another direction. Using ethology (animal behavior, because well we're animals too) in most cases there are well-defined limitations of reproduction based on what sex you belong to. The males' ability to reproduce is limited only by the availability to mate. The number of mates or receptiveness of females are the limiting factor of reproduction for males. They could potentially have thousands of offspring if the females are available and receptive to such an advance.

In females there is time factored into the equation. They can only have so many offspring in their lifetimes (slowed down by gestation etc.), and raising a child is resource expensive. In most cases this means there is a prioritization of what resources a male can offer to the offspring. There are so many examples of this in nature over and over again.

Unfortunately this leads to an expendable attitude towards males. When men talk about their new girlfriends, their friends ask, "What does she look like?" With women in the same sort of circumstances the question is, "What does he do?" I would argue that there are different degrees of quality in mates (males or females), but I would guess there are far more men alone than females alone. Also, extend this with the general toxic expectation from male social groups, and society at large. Men have been taught to eat their feelings about things and if they don't want to be alone, well, just deal with it. This has almost become a bias in sexual selection at this point, females increasingly have higher (unrealistic) expectations (as their mothers did), and males that deal with this bias are the ones mating. If you believe in evolution (I do), this could be a possible explanation. Now extrapolate that with unrealistic expectations in multiple capacities that are perpetuated by social media and you have a recipe for disaster.

Think about what the average female says she wants in a mate and input some of the results here: https://igotstandardsbro.com/.

Result for a hypothetical baseline: A non-married (monogamous), non-obese, 6'0 tall, any ethnicity, 20-40 year old man, making around the average salary ($50k), in the US is about 1.5% of the population.

I don't see this as being far off from the bare minimum that females typically say they want.

I can agree that there may be some men that have extreme character flaws within this population. Some people ultimately won't be desirable. But there is something suspicious going on with the status quo. Population decline is happening across the board with few exceptions. While it may seem misogynistic to say stuff like this I would ask anyone to take a look at the experiments by Calhoun with "Universe 25" and mice. The mouse society broke down when the family roles started to fall apart. Despite many iterations of the experiment, population decline happened at around the same point each time. These mice were given what was believed to be a mouse utopia. When males lost a sense of purpose they became aggressive, and began to unweave the structures that made a mouse society work. While we aren't mice, the experiment could offer insight. We are mammals.

I am 100% about supporting women. I grew up with a single mother that worked entirely too hard to make sure I was alright. I don't even know what it's like to have a father really. These types of problems get spun into toxic masculinity, but they are definitely things that we need to talk about before it gets way out of hand. Multiple perspectives are important.

I think guys like @brianphobos and others, are just fed up with the mismatch based on uneven expectations.
