Literally nobody is calling you terrorists for being virgins.
It's the incitements to violence and rape, idolisation of a mass murderer, complete denial of observable reality in favour of baseless conspiracy theories, blatant misogyny & racism, dehumanization of absolutely everyone on the planet that doesn't agree unflinchingly with your toxic philosophy, romanticisation of psychopathy, encouragement of paedophilia, refusal to take responsibility of any sort, constant lies, and your outspoken desire to force women & even children to be disposable sex dolls... THAT'S what gets you labelled negatively.
We don't know what you look like. And despite your incessant claims to the contrary, looks aren't all that matter, and sex is not the most important thing in the world.
If looks were everything, creepy psychopath Elliott Rodger wouldn't have had any trouble getting dates, Steve Buscemi would still be single, and all the "ugly" genes would have been bred out of humanity long ago.
Your entire philosophy is based on BS, your entire identity hinges on ensuring you remain a virgin, and your entire community encourages violence against women for not sleeping with you after you intentionally make sure you keep your "incel" status.
None of your group's reputation is based on your looks - as we've been telling you this entire time, it's based on your words & actions.
