Which of the following practices should be banned?

[Redalgo]

I do not consider myself a social libertarian so much as more socially liberal than most people.

Public sex and unlimited immigration are the options I feel least inclined to ban but probably would review several studies on the possible outcomes before making up my mind.

My support for legalization of Russian Roullete, duels, voluntary participation in gladiatorial events, and sale of oneself into slavery without coercion would be dependent on there also being regulations. Participants have to undergo and pass psych evaluations, minors shouldn't be allowed to participate, and people should retain the right to withdraw their consent - e.g. forfeit rather than die if they choose, break ones contract in slavery to become free again but owe a debt, or otherwise quit an activity at any time if one has a change of heart.

Verbally inciting others to commit murder, sex with consent with a child under ten, unlimited access to weapons, extreme public nuisance behavior, and blockading access to an event or location through a collective protest occupying public land are things I do not think should be legal.
