For the record, my views predate the Manosphere. Some of us have always thought this way or have changed our minds after giving it much thought, and, yes, after doing a lot of research. That is generally the case, when you are in the opposition because your views are regularly challenged.
As you note, women have always worked. That wasn't something feminism changed.
Deaths of despair and homelessness are dominated by men.
There should be no taxes on income, including that of churches.
I don't think feminism is unifying.
I don't think feminism is responsible for everything that is wrong in the world, but also don't think it is a long-term solution to the underlying problems. I think that it is a system that creates false incentives and skews markets, and that is prohibitively expensive, and I therefore predict that it will eventually collapse on its own.
