Abortion has never been advertised as “cool”, anywhere in the world, so I don’t know why that’s where your head goes. Women aren’t idiots - they are, usually, informed about their options, a heck of a lot more than the men fucking them are.
People have always forgotten to take any pill they have to take regularly. Plan B gives people an option they didn’t have before when that happens. There’s no evidence there that Plan B causes people to take the pill less regularly.
