Callwaiting  - Young people "recruit" each other about everything: music, sports, religion, politics, substance use or non-use, fashion, sex, tablets vs laptops, bikes vs cars, republican vs democrat,  straight vs gay, vegan vs meat.  All of it can have an obnoxious, sloganeering, overwhelming, exclusionary pressure to it, a feeling that young people are being "recruited" to one thing or another. It is the developmental age. And the vast majority move out of that need to validate themselves through peer pressure.

As a middle aged straight woman who has spent most of adult life living in gay-friendly communities and social circles,  I remember heated conversations in my late teens/early twenties with gay friends about whether or not I was gay.  I also remember heated conversations with straight friends about whether or not I would get married or have kids. It was peer pressure, which is equal opportunity and developmentally normal. It has been 30 years since I experienced it.
