While the gender issue has garnered much discussion, the same cannot be said of the larger, unspoken issue raised in the manifesto  - the culture of shaming to silence opposing views. 

In this case, the manifesto has been labeled mysogynistic by some in effort to silence debate. We may not agree with the arguments or conclusions. To have an open honest discussion we need to have an environment for freedom of speech and expression subject to hate speech, etc.
