This isn't even close to true. 1. Virginity has nothing to do with friendship. Many people in HS are virgins/have trouble speaking to the opposite gender, but could still have large friend groups or close friendships with a few select people. 2. Friendships and relationships are two different things. You can have a "friendship" with a person. Regardless of your height, income level, or looks. With relationships, it's encouraged to be tall, be able to talk, have good hair, be funny, be decent looking, be of a certain income level or have a certain career and more. You're also actively competing with other people in regards to dating/relationships. Online dating is a prime example of this, where you're filtered out for being average . While with friendships, not so much. Hypothetically, a person can have a "ton of friends", but with dating/relationships people are often selecting that one special person who fits their requirements. 3. There are different levels of friendships. From acquaintances, to people you know but won't do anything with or have no big connection with outside of a big friend group..to even close friends that you'll almost do anything for or help out in their time of need. 4. While being social is a plus, you don't need to be the life of the party to date. And if someone agrees to be in a relationship with you, most aren't going to automatically leave if they find out you have no friends when the relationship starts.
High school virgins arent incels. But yes, they often lack the maturity to understand that talking to opposite sex is just the same as talking to the same sex. Cant blame them, theyre lacking in experience. Whats your excuse?
Friendships and relationships are not completely different things. Friendship is a type of relationship. Being conventionally attractive may give an advantage when talking to women, but if youre putting yourself out there and having no success at all, its incredibly unlikely that your looks are the biggest hurdle. Women arent generally that fussy if they like you enough.
There are different types of sexual relationships too. Whats your point?
Youre arguing against a point that I never made. Im not claiming that women will leave you if you dont have sufficient friends. Im saying that many incels are also lacking in friends and that suggests that their attitude, demeanour or social skills are lacking, which would explain why women arent interested in them.
