The next day, the square exploded with protests, a popular revolution over 18 days that swept president Hosni Mubarak out of power after 30 years.On Thursday, just before the second anniversary of the day that Egyptians took to the streets in the most dramatic upset of the Arab Spring, Tahrir Square hums with a nervous energy. Hundreds of people mill around, sometimes spontaneously breaking out in chants, arguing politics and visiting the recently erected Revolution Museum in the middle of the square. On Friday, Egypt marks two years since the revolution that radically altered the country.Protesters preparing for Friday’s anniversary are seething with anger at the Muslim Brotherhood.Using the same heated language as two years ago, they slam the ruling political party and President Mohamed Morsi, which, they say, have plunged the country into a terrible economic depression.“People hate the Muslim Brotherhood and they hate the system,” says Tony S., an activist with a youth union, who will oversee the main protest stage on Friday.“We need to complete our revolution, not make a festival,” he adds. “For one year we were against the army, now we are against the Muslim Brotherhood. Everyone is against the Muslim Brotherhood,” he says, pointing to a scar on his lip that he says is from a knife fight with Brotherhood members in Tahrir last month.“Revolution means change,” says Magdi, a veteran leader in the Building Egypt Activist group. “Why did we come out for freedom, liberty and justice if the president doesn’t follow the people? [Morsi] is only following his party, the Muslim Brotherhood.“That’s why the people will come out tomorrow. We’re not going to wait four years [until the end of Morsi’s term] without freedom and democracy. If we wait four years, we’re going to stay 100 years without freedom and democracy,” Magdi said.“We came out against Mubarak; we can come out against Morsi. The people in Egypt are not scared anymore.”At the plastic tents of the Revolution Museum, which feature photos of protesters killed in clashes, articles, protest signs, flags and memorabilia, visitors can only enter by stepping on a giant picture of Morsi, a serious insult in Arab culture. Most stomp on his picture with gusto.A., who owns a souvenir store, says inflation has exploded and the black market, which had laid low for a decade, is back with a vengeance, due to the instability.“I was hoping it would get better, but now there is no safety. I cannot walk outside at night by myself,” he says at a coffee shop near Tahrir Square. Two women in head scarves join in to express their disgust.“They’re selling Islam,” says Lila. “People are attracted to the Muslim Brotherhood because they say ‘We’re Muslim,’ but they’re playing with religion, they never mean it.”While anger at Morsi is widespread, Khaled, a medical student, warns that the country needs to be patient.“I don’t like his policies, but I am for the president,” he says.“He has only had seven months, we need more time.”Khaled says the protesters are now more vocal but much fewer in number, and he doubts that calls for Morsi’s resignation will have any impact.On Thursday, Egyptian riot police fired tear gas at dozens of protesters who clashed with police as they tried to tear down a cement wall built to prevent demonstrators from reaching the parliament and cabinet building, according to the AP.Major opposition leader Mohamed El Baradei posted an online video message urging people to come to the protest.“I demand from each one of you, all across Egypt, to prove that the revolution must continue and must be completed,” he said in the message.The Muslim Brotherhood has promised that its members will not attend the demonstrations during Friday’s anniversary, ostensibly to avoid violence, though many protesters doubt they will stay away. The Brotherhood announced that it would renovate 2,000 schools, plant trees and deliver medical aid as part of their charity efforts to win over poor voters.The greater possibility for violence is on Saturday, when the final verdict is to be delivered for the suspects in the February 1, 2012, Port Said Stadium massacre, when 79 people died in riots at a soccer pitch. Eyewitnesses said police did nothing to stop the melee that broke out between rival soccer teams and even refused to open the doors to allow people to escape. The massacre was held up as proof of the country’s slide toward anarchy.If the suspects receive light sentences, the ultras, soccer hooligans who are often at the head of protest marches and responsible for much of the violence at Egypt’s recent protests, have promised to destroy and burn buildings in Cairo, according to Internet posts by various factions.
