It seems that there is a decent though small percentage of the male population that are "Nice Guys^TM", befriending women, developing attraction for them, asking them out on dates, and then expressing anger that they are being rejected. Some of these men express this anger toward the object of their romantic interests, while others are angry at all women for not seeing how attractive they are. Women often, quite rightly, call these guys "entitled" for expecting their friendship and human decency to result in attractiveness, which is much less related to our character as human beings than many of us would like. However, many men see the shouts of "entitlement" as a personal insult. They perceive feminists as shaming them merely for desiring romantic relationships, rather than for their failure to deal with rejection gracefully. Some of them are angered by this, and turn to ideologies like TRP and r/incels in despair.

What would you suggest for these men? They're clearly dealing with a lot of issues, like the human drive for intimacy, socialization that leads them to believe that caring in and of itself is attractive, and frustration at not being able to achieve something that society tells them everyone should be able to have. It isn't simply that they are lacking in attractiveness and attempting to punch above their league, but that they believe that apparent goodness of character confers attractiveness, and they're angry when that proves false. Some of them sadly embrace their darker sides and come to believe that women are attracted to cruelty. This isn't the magic bullet they think it is, though.
