For me, accusations of entitlement levelled against men, especially low-status men (like "nice guys") have never seemed right.

When a man is denied something the usual reaction is "what is wrong with me?" That isn't entitlement. That is "I have somehow failed to meet the standards required to get what I want" or "i don't deserve what I want."

Compare that to the many women asking questions like "where have all the good men gone?" This is entitlement. This is "I am not getting what I deserve." It's not "there's something wrong with me" or "i have failed."

All I am aware of that men say which could indicate a sense of entitlement is "women want jerks, not nice guys." However, the least charitable interpretation of this is "I have put in the work so I deserve a woman." Even this is less than the entitlement displayed in the female example. They don't feel that they automatically deserve a woman. They feel they have to work for it. They just feel that they have worked for it. You don't need to earn an entitlement.

As a man who has previously expressed similar sentiments I can however say that this inchariyable reading is not what is meant. It is an epresssion of frustration with the fact that what many women say they want in a man is not what their choice of man indicates they want. It is innacurate but not entitled. It is a reaction to hearing women who have no problem finding a boyfriend, complain that they can't find a guy who treats then well while they, a guy who treats women well, cannot get a date.

The proof of this is the shame they feel at not having a girlfriend. You don't feel shame for being denied something you are entitled to. You feel shame for being unworthy.

I can only interpret accusations of male entitlement as projection.
