Im pretty sure an incel blames women for not being able to get a relationship.
Its the change in mental framing from "maybe i should work on myself" or "i just havent had the right opportunity" to more of a "women hold too much power over me and are playing with me" or "ive done everything right, women owe me this"
Wikipedia sums it up better than i can:
Description of incels
The subculture is often characterized by deep resentment, hatred, hostility, sexual objectification, misogyny, misanthropy, self-pity and self-loathing, racism, a sense of entitlement to sex, blaming of women and the sexually successful for their situation (which is often seen as predetermined due to biological determinism, evolutionary genetics or a rigged game), a sense of futility and nihilism, rape culture, and the endorsement of sexual and nonsexual violence against women and sexually active people.

So, unless you find yourself blaming/resenting women, then you arent an incel. Your still just figuring things out like tge rest of us!
