Thomas Sowell wrote at length about that in Vision of the Anointed; constrained vision (that's us) vs the unconstrained vision (that's the social engineers).
Except when it comes to gay "marriage"; then we're accused of wanting big government engineering relationships.
Sigh.
It isn't that we want to "engineer" relationships. It's the difference between recognizing the inherent rights of others versus civil rights that are invented.
Life, liberty, and the pursuit of happiness only require one person to be exercised, therefore an inherent right.
Marriage, however, requires a MINIMUM of three people (as does voting, except in a married couple): Two to be married, AND ONE TO RECOGNIZE THE MARRIAGE.
Now, I don't care that your daddy didn't love your namby pamby, whiny little miserable self enough when you were a child, I'm not going to go out of MY way to make up for your personal problems because you don't feel you got enough recognition as a kid. Now shut the heck up, already. And if your 7th grade science fair project wasn't so dumb, you might have got a passing grade.And here, here's a Kleenex.
