The important part isn't whether it makes children gay or not -- though I'd argue in a culture that is more accepting of such things and praises that identity more children will likely indulge in such behaviour -- the most important part is the sexualization of children which was a major post-war project in Western Europe which was, as acknowledged by many of the 'scientists' who headed the programs, a form of 'anti-fascist' social engineering. Please see this article which I posted the other day which describes the activity of a 'sexologist' named Kentler who was a German homosexual, child rapist and anti-fascist.

He oversaw a West German project which actively sought to provide young boys to known pedophiles specifically because men like his 'inspiration' Wilhelm Reich and other Freudian nutcases had theorized that Fascism or the Fascist disposition -- later renamed the 'authoritarian personality' by the Frankfurt School -- was a result of neurosis caused by childhood sexual repression and that the cure to all this was the sexualization of children and the general population. Nothing has changed and these ghoulish experiments have just taken on different forms including what we're seeing today. The real question is why time and time again you see the same types of people trying to place sex at the front and center of a childs life not whether they will become gay or not.

The answer to that question as to why this do this, so succinctly summarized in the New Yorker article I posted, is to 'prevent another Auschwitz'.
