Lefties are (usually) big on the FREEDOM part of citizenship, but are out to lunch on its counterpart: RESPONSIBILITY.
To the Left it is unreasonable to expect "birthing humans" and their spouses, if applicable, to make a rational decision about whether to procreate, when to procreate, and how to care for their offspring. Every middle-class couple in the country carefully considers whether to have children, how they are going to be taken care of, what the costs will be, and decides whether or not to procreate based on an assessment of those factors. Sometimes (often) they delay having children until they have the resources to nurture them in the way that they choose. Sometimes - good heavens! - they decide NOT TO HAVE KIDS, because they can't afford it.
But to a Leftist, kids are sprinkled around the population like some sort of an unavoidable communicable disease, and it is Government's role to ensure that the offspring are taken care of - funded of course by the middle class folks who have acted prudently.
The Left is evil. No denying it.
