These aren’t mutually exclusive categories:
Controllers – Just do it our way because (a) we have “science/social justice” on our side; (b) because we want it that way even if the “science” is phony and “social justice” is nothing but a slogan; and (c) we have the power to make you do it our way, and we love to use power.
Risk-avoiders — Somebody somewhere was harmed by something, or might be harmed by something, so we’re going to enforce some rules in the vain hope of preventing more harm, and we don’t care (or even think) about the cost of those rules in foregone economic growth, employment, personal liberty, or self-reliance (i.e., learning from experience).
Misguided libertarians — Liberty is okay, as long as it doesn’t have consequences of which we disapprove, such as any kind of discrimination, (relative) poverty, or the merest hint that an innocent person has been imprisoned — in fact, “too many” people (of the wrong color) are in prison (even though the crime rate is much lower as a result). And liberty means the absence of violence except in the final (probably futile) throes of self-defense (if then) because everyone is a sane and reasonable as we are.
Free riders – Hey, if government is giving away “free” stuff or granting privileges to certain groups, I’m all for more government (I just don’t want to pay for it).
