Immigration and "illegal" people. It should never (ever ever) be "illegal" to work for a living; it makes no sense to criminalize labor. It should never be "illegal" to migrate -- travel, along with Free Press, is one of only two guarantees of Freedom.
School. It should never be compulsory to attend school; that turns "education" on its head, and is why schools become devoted to Control instead of discovery and problem solving.
Pollution. Build anything anywhere -- products, factories, whatever. But if what you made has an "exhaust" pipe or chimney, or a "waste product" of any kind, including any solid, liquid, gas, noise, or smell, or if it creates an environmental impact such as a bottle-neck, traffic congestion, or nuisance to a neighbor, then you pay for the cost of that impact. Mitigation by the following design principal should always be recognized: Whatever you build that has an exhaust pipe, it must vent into the face of the user FIRST, before it vents into the faces of non-users; whatever is discharged, must first be vented into the water and air system of the maker/manager/owner, before discharging into the sewer or environment.
Religion. Redemption and Rapture can only be experienced individually; no priest or principal can "save" anyone else except upon proof that they have taken their own advice and have saved themselves. Anyone who proclaims a religious basis for killing any other person should be prosecuted for murder, as plainly as any other such solicitation made without the claim of sanctity.
Theft. Title to material goods never passes by theft. You steal something by force or fraud, it is never yours to use, sell, or profit from. You buy something without title, it is the same as if you stole it from the true owner yourself.
