True Left

Getting back to "White" "leftists" reproducing, I have noticed that those who were initally closer to the True Left slowly began to abandon their leftist views as they aged and reproduced, while those who did not reproduce stayed true to the same views. I have actually seen numerous cases of this, now that most of Gen Y leftists have reached the age at which they decide to reproduce or not.

This coincides with the False Leftists, again mostly those who have reproduced, showing their true colors, and increasingly asserting their "White" identity (e.g. being critical of "wokeness" etc.). In contrast, True Leftists (many of whom have NOT reproduced) are fully supportive of "wokeness", and only invoke their "Whiteness" to say "it is my duty as a 'White' man/woman to listen to the concerns of 'non-whites' and allow them to lead the movement", so I would assume that they implicitly recognize the tribal nature of "Whiteness".

Is this merely a coincidence? Or is there some biological explanation for this? Or am I simply looking too deep into it?
