Many people have different views on this. This is my take. There are many good reasons for the Manosphere’s existence.
Perhaps the most important is triage; to stop the bleeding. Men have been deceived as to the true nature of both women and the system. Coming to understand the situation is termed “taking the red pill“. Most importantly it gives men the information they need to make decisions in their lives. Often the alternatives are not appealing, but it is better to make informed decisions rather than to go blundering into the unknown. And then there is the peace of mind aspect to this. Men who have been treated poorly can come to understand why things were the way that they were. This does not necessarily fix anything, but it does give a measure of closure.
Another reason is to affect change. There is not agreement on what change, and how it may occur. But most everybody can agree on the need to educate more men with respect to the red pill. That is why I am here.
A third reason is to develop the knowledge that academia won’t touch. If they won’t do it, we will. If there is a complex problem, it is important to model it effectively. If one does not, then it is very difficult to make positive suggestions. Models are useful in predicting the future, and that type of capability is what is needed here.
A final reason is to document for posterity how and why things went wrong. Perhaps they can learn from our unfortunate example.
If anybody has other reasons, please chime in.
