The second is of a poster being displayed at train stations in Toronto, Canada, with the campaign title "The sex you want" and showing a picture of a homosexual threesome:
The instinctive reaction most people will have is that exposing children to these images is an attack on their childhood. And yet public authorities clearly believe the opposite - that it is either a good thing, or at least harmless, for the images to be displayed to children.
I understand the position of the public authorities, even if I think it is wrong. The liberal idea, dominant in our society, is that the individual autonomously determines his own goods and identity. But, as all desires are equally desires, they all have to be acknowledged as equally valid, as long as they don't claim primacy over others (which, for liberals, is the sin of "supremacy" or discrimination, intolerance, bigotry etc.) So the public authorities, following this liberal credo, don't really have a principled way to object to the imagery, without exposing themselves to charges of hypocrisy or inconsistency or lack of principle.
It seems we are witnessing another step down in liberal culture. Liberal culture had previously compromised by rating materials for their sexual content and allowing parents some control over what their children were exposed to. Apparently the aim of being inclusive toward transsexual and homosexual culture (making it normative) is now overriding the older compromise - it is now thought progressive to habituate children to these things.
And yet there is damage being done. The message being given to children is that sexuality is to be freely pursued in any direction and that there are no sexual impulses to be restrained or held in check. They are being exposed to forms of sexuality that are at the end point of what happens when restraints or modesty or checks give way.
This is especially problematic for those children who will later seek to form heterosexual relationships. Within homosexual culture, it does not matter so much if the emphasis is on fleeting sexual encounters for their own sake. But a heterosexual culture can't work this way. A heterosexual culture has the more difficult aim of bringing together men and women for stable, monogamous pairing, with the aim of raising children successfully and carrying on an intergenerational family tradition. This requires both men and women to integrate the sexual aspects of their relationship with other purposes relating to the good of children, family and society.
In short, sexuality has to be ordered toward higher purposes. A man cannot just follow his libido if he is to commit to a lifelong role of husband and father within a family and secure the material well-being of his wife and children and help to socialise his children toward a successful adulthood of their own. Similarly, a promiscuous woman damages her ability to pair bond with a man and to form a respectful and loving emotional relationship with a future husband.
If children are allowed to mature without being precociously sexualised, and within a culture that orients them toward marriage and family, then they are likely to reach early adulthood without having lost the innate qualities that might allow them to successfully pair bond with a person of the opposite sex.
And that's the sense in which we instinctively believe that it is possible for children to be corrupted, and that children need to be protected from certain types of sexualised content. We don't want our children to lose what is supposed to be intact within them, emotionally and psychologically, that allows them to successfully marry. It is our job to at least get them to independent adulthood, and the age of marriage, without this having been lost.
This requires not only good parenting, but also agreed upon social norms and standards within public life. And this is where liberalism is increasingly undermining the role of parents in the raising of their children.
