This is because they have adopted and are mindlessly following the Marxist revolutionary edict of destroying the family to subvert capitalist society without understanding the origins or purpose of that agenda. The result is that they are destabilizing whichever stable society might potentially exist. Effing Leftist idiots.
And I should add that the less scrupulous in the Left don’t have a problem with establishing a dependent class with handouts, something that has worked very well for them politically so far.
Just watch the show Lockup on MSNBC. Almost 99% of the inmates had an absent dad, or one who was locked up in jail.Not the best role models for kids, no matter what the race. And the predominance seems to be in black families. No dad to teach a young son how to behave and you get a young thug who starts ripping off people at the age of 10.
