You're not entitled to a relationship is the fact of the matter. It should be treated with respect and not as something you are owed.
You know why? Because the man or woman on the other end of it is a person with a whole lived experience, feelings and capacity for love. They deserve better than some bitter resentment at never getting something you were "owed by destiny".
I think pretty much everyone deserves to be in a relationship for the same reason I think everyone deserves to learn how to ride a bicycle, or read a book, or learn to swim or have a friend or get a job. It is simply an experience that I think everyone should experience at least once in their life.
People aren't entitled to a relationship? In what sense? Legally? sure. The fact of the matter is that on a basic level, most people expect to find love in their life. And whatever institution that interrupts most people from achieving normal life goals like having a decent-paying job and having a normal relationship will either be torn down or will tear down society with it, whether it's AI automation of jobs or dating apps or whatever.
I am also a human being with an entire lived experience, and I am done with people like you belittling me. I have my own goals, and I am going to achieve them regardless of what people like you think. Is that entitled? So what? A lot of my difficulty in dating has been building my confidence and overcoming this notion that I don't deserve anything instilled in me by people like you.
I am not resentful or bitter, but I am angry at people like you for misrepresenting my beliefs and presenting your own perspective as "fact", when in fact you are the minority. Most people do feel entitled to a relationship, whether or not they say so.
People say this to feel better about the situation with zero regard for the insidious societal issues it causes. It's absolutely true but it's basically never productive to make a point of it. For your own good and the good of society, develop more helpful insights or don't say anything at all.
Going through life with basically zero romantic opportunities will completely fucking fry the brain of an average human. Sex, romance, etc. are a top psychological priority to ensure the continuation of the species and most people on this planet are hardwired to be in pain in the absence of it. With some luck, people hurting like that hold on to some hope of things changing for them and it provides enough motivation to break even on societal contribution.
If they give up hope, our society is structured in a way that doesn't give them any reason to play by the rules any more. If you're holding down a good job, blow your money on stupid shit; you have no wife to disappoint and no kids feed. If your hobbies consist of jacking off and playing video games (these are super easy, so you should definitely consider them) just half-ass whatever job lets you squeak by on rent if you're not fortunate enough to crash at your parents' place indefinitely. Get super into drugs, you're not really hurting anybody but yourself. Your friends might think you're a fuckup, but they're busy with their family and don't have a lot of free time to spend with you, so you don't have to be ashamed of your situation all that often. 30+ years of no responsibilities other than don't die (and even that part is kind of optional). Gonzo lifestyle. It's all yours, baby. It's lit.
There are people out there that are just plain bitter, unstable, unable to be reasonably loved, and maybe even ugly to boot. There's not much to be done about that. That being said, in the modern era, it is very possible (maybe even easy) for good people to never form any romantic relationship that would tie them into productive society, and turn into burnouts with apathetic, bitter worldviews. "You aren't owed anything and you got what was coming" is not encouraging in the slightest.
