I keep seeing this repeated throughout every thread about incels and more generally relationships and I can't help but feel slightly weirded out.
Unless you believe in some ridiculous Randian or equivalently fucked up ultra libertarian ideology, the notion that "you're not owed anything" is obviously bullshit. We live in arguably modern societies. We're already owed shit. Our physical integrity, our right to property. Depending on how far left you stand you could claim that we should be owed medical care, food, water and a roof. All these things belong in the material realm. I would personally argue that our societies should ensure our spiritual/mental well being as well, something that they fail miserably to do so far. We know for a fact that relationships are an extremely important factor in mental well being. This doesn't necessarily apply to everyone, but physical and emotional intimacy are evidently important to a large part of the population.
I think it's important to clarify that I'm not defending or advocating for incels, but I don't believe people turn to hateful ideologies out of thin air. The initial malaise that set them on their path is real. Loneliness can and will fuck you up. In that sense, it is society's duty to keep people from falling in the same trap, which is obviously a lot harder to do than giving food to someone hungry or shelter to homeless people, because you can't just "give" relationships. You can only give people the tools to let them help themselves. And I'm not sure "tough shit, you're on your own, learn to be happy alone" is particularly useful in that regard.
