People throw the 'incel' term around alot, including incels themselves. What they actually mean is that their standards are too high for what they bring to the table, and that they aren't willing to stoop to the level of romantic partner they deserve quite yet.
Lucas, on the other hand, is truly involuntarily celibate. A combination of his repulsive physical appearance, hygiene, and various mental illnesses disqualify him from ANY dating pool.
Honestly I think people focus a little too much on personality and social value when talking to Lucas, well-intentioned or not. Even if he was the most charismatic, confident person in the world, Lucas's face, body, clothing, style etc. are absolutely revolting. People are naturally repelled by Lucas and there's a good reason for that, biology. Lucas is a greasy, wrinkly, balding, obese pedophile. His facial hair grows in disgusting blonde patches. He smells like cat piss and vinegar.
Fuck you Lucas if you're reading this. I hope you puke while you're passed out on your back in the park.
Yeah, but when have incels ever been known for having realistic standards?
