I've seen this tweeted: “Plan B is an abortion pill. Stop funding the Plan B abortion pill.” Wrong. Wrong. So insanely wrong. Semen can live up to 72 hours inside of a woman’s body, and therefore they have 72 hours to attach to an egg to make a woman pregnant. Plan B, offers a high dose of estrogen (similar to what is found in your daily birth control pills) and prevents the specimen from attaching to the egg. If the sperm has already attached itself, Plan B will make the woman sick and nothing more. The female will still be pregnant. It does not kill a fetus, does not kill sperm, and does not do anything other than preventing attachment. Plan B is not an abortion pill; it’s simply a high dosage of estrogen to prevent the sperm from attaching to the egg and making the woman pregnant. Funding Plan B is not funding abortions, its funding pregnancy prevention. If you're against pregnancy prevention, then yes, this is against your beliefs. But if you're pro-birth control, and anti-abortion, Plan B falls under your belief system.
Before you criticize (especially if you are a male, with no uterus, and none of the aforementioned issues) DO YOUR RESEARCH. There is nothing more frustrating than an uninformed voting pool.
