Two criticisms that come to mind are:

• the cause of the epidemic is the patriarchy, therefore it’s men’s own fault, i.e. the rigid gender roles and “man up attitude” are within the power of individual men to overcome and they just need to um… man up and break down those barriers.
• the cause of the epidemic is men trying to cling to the benefits they would have otherwise under the patriarchy and it’s a reaction to non-men having more status and freedom.

(Before you hit reply please remember OP didn’t ask for an discussion on if these are real or correct - just what some of the criticisms are. I’m not saying I buy into either of them.)
