If you could wield global influence, what things would you have banned?

Cigarettes.

MTV, and all programming associated with it (I think MTV is responsible for Jersey Shore, for example).

Mosquitoes, flies, wars and loud rap music.

Every day I would think of something new. Today it is litter.

Star Wars movies written and directed by George Lucas. ( except episode IV )
Dictatorships
Nuclear weapons ( except against canibalistic aliens and rogue asteroids )
Ethnic cleanings
George Clooney’s line-up of women waiting to be his 3 year squeeze

religion having any influence on government whatsoever.

Passports – as in unrestricted travel would be allowed

I’m a libertarian; we’re pro-choice on everything.

I’d ban state-enforced bans.

Hungarian sitar players.

They know what they did.

Nothing, except capital punishment.
As soon as you ban something, you create an underground movement that festers in the dark of secrecy. When it emerges, it is more of a problem than when you pretended to eliminate it by “banning”. Banning is really sort of a stupid notion when you think about it. Nobody can erase a human impulse by declaring that it is banned. IMHO, it requires a sort of immaturity to imagine that banning some thing is a solution to anything.

As stated, I would ban capital punishment. No institution that is dumb enough to imagine it can effectively ban anything should not have the power to snuff a life as a result of the occasionally incorrect and/or corruptible judgement of a fallible judiciary.

Myself, i’d ban racism, homophobia, sexism & sales assistants who immediately pounce as soon as you enter the shop, “Can I help you sir?” Yes, fuckoff!

I would say ditto on what @Neizvestnaya wrote.
