It has been said and it is being said - again and again in a self-congratulatory tone - that it is a good and effective strategy (here and now, in the Western cultures) to meet people half-way inside their secular-prejudices; and address their politically-correct Leftist blindness, nihilism, hedonism, active propagation of evil... with alternative information, arguments and perspectives.
The argument that New Right secularism is a kind of Entry Drug to Christianity.
(Christianity being indispensably what we really need.)
It Doesn't Work - and that is fact, not my opinion.
Rare individual exceptions aside (and these exceptions mean nothing when it comes to strategy - even when you personally are one of the exceptions) this does not work, and we know for sure that it does not work: therefore we should give it up.
We know it doesn't work because a generation of The Internet.
Alternative information, arguments and perspectives are by orders of magnitude more available now than ever before in the history of the world, and yet - look around!
If not, then what?
Uncompromising statements of the reality of things, truthfully, explicitly, as best we understand it.
Nothing less will suffice.
