Of course, an authoritarian government like that in Putin's Russia can push the idea that open presentation of "gay values" can discourage "marginal" people (or "waverers") from wanting or trying to have children and raise families, and threaten the country's future collective strength, and exacerbate problems of an aging population ("demographic winter"). That sort of thinking wasn't too carefully concealed even when I was growing up, when there was a baby boom. Then, it was certainly "irrational."
By the way, I've seen outdoor pictures of Putin, shirtless. He has reason to wonder about men becoming "marginal".
