The truth is maintaining healthy family relationships is difficult enough, let alone having and raising children. It's much easier to get a dog and then have the free time to go to Coachella on the weekend. No parents in sight, a generation of hedonistic babies that discover "adulting" when they hit 34.
And this doesn't even need to be a God argument, Darwin alone would say what we're doing is self-destructive from a biological point of view.
On the topic of Christianity in relation to the posted article honestly my first thought was that we were commanded to "Go forth and multiply."
>>I ask myself, is there some behavior or value that we are allowed to judge people on?
... of course, you will be judged by a lot of readers for your religion beliefs and traditional moral framework
Anyways, the point stands - should we tolerate everything, at all cases, always? Doesn't sound right to me
Other reasons, as far as I can see are:
The destruction of the concept of (nuclear) family. The abject sexual promiscuity and the normalization of it.
The decadence of the Western civilization and the disregard of the values congruent with Christianity resulted in the state that we are in now.
We see the moral values (or worse, the 10 commandments) as something that's archaic, that has no place in a "modern" society and we absolutely tolerate everything and we are afraid of shaming things that should be shamed (based on the effects they produce).
I ask myself, is there some behavior or value that we are allowed to judge people on?
Who do we think we are that we normalize every single demented thing, and additionally we think we have progressed our civilization because of it?
Don't we study history?
