Find anything that can enable identifying a homosexual... Go ahead...
OR stop promoting the leftist propaganda of the existence of a homosexual innate identity...
Listen cowboy, I don't know if it is innate or not, or environmental, or a mixture of the two, or whether it varies by the individual (my guess), but the suggestion that going gay is like picking a brand of toothpaste (I assume that is what you meant by claiming there are no gay people), simply defies all anecdotal evidence. The anecdotal evidence is that folks resist going gay, until they realize that further resistance is futile, and destructive to the self (psychologically).
