Except you have it wrong.
Its the opposite, actually. Let me draw it clearly for you. Imagine Toxic Masculinity as a tree. And on this tree, are various branches. For this visual picture, let us say this tree has branches representing sports, military, entertainment, and as a subset of entertainment the "Geek" culture rigidly attached to that branch.
Now you, you propose we work to solve the issue of harassment, such as this, from the geek culture. So we cut off the branch. Hope it grows back right.
But it wont. Itll grow back the same. So we cut it off again, and still this toxic part of the geek culture keeps growing back. So you, in your infinite wisdom, proclaim "It is the Geeks branch which is defective. We must keep cutting it and forcing it to adhere to a how the healthy branches are."
That wont work. To summarize, you are not looking at the root at the problem. You are looking at a mere scab, and proclaiming that once we cure it, it will never grow back. No, that is merely a scapegoat to the larger problem.
You are merely looking at a page, and not the whole book that binds it. You are looking at a frame, and not the whole house that keeps it. And you proclaim that it is that frames fault and that we must fix it and only it, and that anything else is deflecting the problem of the frame, when it is in fact the house that is falling apart.
Now, my dear dity, if you so not understand what I am trying to convey to you, than alas I must submit that not everyone can understand complex issues, and that I must leave you painting one plank of the whole fence, as you try to blame the plank for not fitting in with the rest of the fence.
