It depends on the context tbh.
The various internet communities that have sprung up these past two decades all touched on a very real issue, that is, the loneliness and social alienation within modern society. In that vein, yes, individuals do have the right to vent and grieve about the struggles and losses they experienced in their life.
The problem is where we are at now, the vast history that lies behind us and where that discourse spanning many years has taken us to today. Blackpill theory and Incels.is have become the dominant mode and culture through which discussion about the topic is now perceived and interpreted. The Blackpill on its own is rather innocuous, it's common sense really. One can without too much difficulty grasp how genetics and looks have an observable impact on people's lives. In tandem with the culture of incels.is, however, the two make for an ugly pairing.
The incelosphere is a wasteland of tortured souls, many of whom use the Blackpill to justify their own self-inflicted suffering. In addition, by their edgy and provocative nature, the forums also attracted psychopathic, narcissistic and mentally unstable individuals, which connects to what
@cosmicx16 was alluding to in his previous post. Incel culture doesn't really offer any real solutions. It's quite fatalistic, and it is expected that individuals wallow in their misery after being faced with the 'inevitability of the Blackpill'. Serge attempted to address this with the Whitepill a few years back, but as we all know it never gained very much traction.
