But the current drive from society to try to emasculate men at all cost is indeed worrying.
I think you're using the term "emasculate" in a very emotive way, and citing what you view as extremes of "emasculated" behaviours.
Firstly your stereotype "soy drinking, beardy, chihuahua walking" etc. In modern society there's no need for a large, aggressive guard dog, dogs are pets pure and simple and I really can't see why a smaller dog should be seen as weakening a man, these animals are fearsome ratters by nature and when brought up e.g. in a farm setting. The only reason in modern society for a pet dog owned by a man to always be big & macho is to make a statement by association with the animal - and a man who is confident in himself doesn't need that kind of symbolism. Sort of like the old "big car = big penis" thinking.
Regarding soy/non-cow milk, humans were lactose intolerant until very recently in evolutionary terms and cows milk still isn't very good for the majority of people. More and more people are realising that consuming something that isn't really that good for you isn't a terribly good idea, so are going lactose free whether that be soy, almond, oat, goat or any other lactose low/free variety.
Beard wearing is a ridiculous indicator of someone being emasculated. Fashions change, and many times in the past beards were an indicator of masculinity and clean shaven was seen as effeminate.
I can completely understand the desire in men to be protective of women. Women are physically weaker, have times when they are pregnant and less able to defend themselves, and due to these have historically been the ones to raise children.
They are also in many ways less "disposable" than men. If the men go out to hunt & only half come back, the remaining ones can still father the same number of children. Whereas if half the women die, you can only produce half the number of children.
BUT - the world has changed an awful lot since the caveman days or even medieval days.
Modern warfare rarely needs massive muscles and the ability to club or punch an opponent into submission, or the levels of face to face aggression it once needed. Brains, co-ordination and the ability to use modern weaponry are much more important these days. As long as physical strength isn't in the equation women can do everything men can. There are women soldiers, sailors, fighter pilots, "on the ground" not in back offices.
With changes in modern society bearing and raising children is no longer a dangerous potentially fatal task and can be much less time consuming e.g. modern medicines, schools, formal child care arrangements, modern technology. This frees up women to work, despite them often being expected to still pick up all the home tasks like cooking, cleaning, childcare & admin.
So women have in general adapted to how the world is now, at least in First World countries. They can fulfill just about any role without feeling de-feminised or masculine. Many men have adapted in the same way, sharing tasks and no longer dividing things into "men's work" and "women's work", as there's no need for that any more.
Unfortunately many men have failed to evolve. They don't seem to realise that being able to fight and/or oppress anyone weaker than them (in their eyes) is no longer an important trait for survival. This can frustrate them and they react in the only way they understand, by getting more violent & aggressive, often against the very people they should be protecting.
TL:DR
It's a very sad state of affairs when the whole historic reason for men needing to fight & be aggressive is turned against the very people those traits evolved to protect, rather than being able to adapt to the modern world.
