I don't think UL is screening by age but by lying. However screening by age is how the SOFTWARE WORKS period, it's a major criteria one puts in for searching and there aren't that many criteria usually (one can't demand only brunettes so easily as they can only 30-40 year olds), and when people are subject to the design of software ...Maybe instead of screening by age you need to take a closer look at those SJWs you dismissed.
