One of the core principles of the red pill is game, otherwise known as the ability to attract women. And one of the core principles of game is that nice guys never get anywhere. The nice guy routine fails because behaving like a ‘nice guy’ betrays the principles of masculinity and of being a man. To be a man is to be strong and unyielding. To be a man is to stand for something, to fight for something, even to die for something.
To be a nice guy is to take any position or utter any banality just so long as it inches you ever closer to your eventual goal of scoring a night of sexual activity with the unfortunate target of your romantic affection.
In other words, the nice guy not only has no principles of his own; he actively betrays what it means to be a man while he seeks a reward for being a man. Which is why this strategy is a never ending series of failures.
