This toilet is so fucking brazen and mask off that I thought it was a fake account or something. But it is a 9-month account, it has karma, it has activity, it's real.
Now let's think for a second. Why does insecurity exist? Why are men insecure? And what is the difference between a confident man and an insecure man?
Simply put, a man is insecure because he is aware of his own shortcomings. He is aware of his own negative parts. He knows he has an ugly face, he know's he's short, that he has a small penis, that he doesn't have experience with women, that he's poor.
And naturally, a man is confident for the opposite reasons: he knows he has many positive qualities, he knows he is good looking, he already has positive experience with women, which further boosts his confidence. He knows he has a chance.
So by hating 'insecure' men, they are essentially hating ugly, poor and socially awkward men. They are hating subhumans.
Also jfl at the comments, literally all of them are saying how insecure (ugly) nerds are worse than good looking rapist jocks.
