With respect, there are some errors in your thesis. Specifically, you're attacking some strawmen.

Here's the steelmanned version of the ideas you're saying are causing issues:

- Instead of defining men / women, think of each human as a person. There are no strong men, sensitive boys, intelligent women, vulnerable girls - there are only strong people, weak people, hard people, soft people. Our job as society is to compassionately accept people as they are and encourage them to be their best authentic selves, instead of arguing there is some role they must force themselves to fulfill because they were born with a set of genitalia, because this promotes individual happiness and is the kind thing to do.

- People's virtues are learned, not innate. Independent people can learn to accept help. People who are unsure of themselves can gain confidence. People are allowed to be vulnerable, but also to have the space to find roots, solidarity, strength and growth. Roles that traditionally would have gone to someone with a penis - head of household, soldier, provider - are achievable and manageable by anyone, because the virtues needed to hold those positions are learnable and not rooted in biology. The same holds in reverse - roles that would traditionally have been held by women are open to everyone.

- People should be given freedom to flourish as they best see fit. They have rights to their bodily autonomy, securing their financial futures, achieving scholastic pursuits, respect and equality for their contributions, and more. Historically, this has not been the case, and this does not just apply to women's rights here - it applies to anyone who has had these opportunities denied.

- Some human but deleterious attributes we should all grow beyond. Brutishness is an excellent example - as is shallowness, closed-mindedness, entitlement, ignorance, greed, dishonesty, and more. Some attributes are contextually awful - being stoic, for example, is a boon when you need to handle stressful situations, but it can also manifest as a lack of empathy for other's emotional lives.

Note that none of these are attacking masculinity - if anything, point two contradicts exactly that, literally anyone can learn the virtues associated with masculinity and is why trans men are supported even conceptually. Rather, point four holds - there are a subset of awful virtues that are unacceptable or contextually awful from anyone that have been attached to being a man, such as entitlement to sex, resorting to anger in lieu of healthy expressiveness, and assuming they must shoulder all burdens instead of being allowed to seek help. In other words, mainstream movements are attempting to abolish toxic masculinity, not masculinity itself.

You discuss the emotional needs of boys and girls as being different (which may or may not be valid, depending on the best available evidence), but then you argue that treating boys like girls is not the right thing to do, which is not what anyone is proposing at all. Again, the idea is that people are people, not their bodies. Girls and boys are people, capable of feeling, wanting and expressing the full range of emotions. People want to treat children in ways that allow them to be emotionally expressive and mature adults.

Further, when you talk about the patriarchy, you are again not taking point one and two into account. Nobody wants authority, strength, boldness, vitality, etc. to go away - these are all great virtues. Rather, they want the idea that these qualities are somehow gendered to go away. If you want strong leaders, find them in both genders. Additionally, historically, the patriarchy you are discussing has tended to enshrine point four virtues rather than eliminated it - it's the same system that inflicted foot binding tortures, made Indian women throw themselves into funeral pyres when their husband passed, allowed female infanticide to flourish, and so on. These are all terrible things and bundled into a parcel of ideas about what men "should" be: not just protectors, but architects of their offspring / wives / sister's fates. We have managed to overcome many of these core underpinning beliefs, but there still remain a lot that should not go unchallenged.

So, respectfully, I would ask you to at least attack the right thing. It is possible your value systems are opposed to all the points above, and that's fine. But if a value system has to reach towards attacking strawmen of other viewpoints, then it is not a good sign that that value system has been arrived at fairly.
