Protesters took to the streets in 18 cities across Mexico on Sunday, demonstrating against the policies and comments of U.S. President Donald Trump. A protest in Mexico City drew more than 20,000 people near the U.S. Embassy, with the crowd showing a sea of flags showing Mexican pride and signs with anti-Trump sentiments. “We are sending a message to Donald Trump: No wall. No immigrant raids. No aggression to Mexico,” said protester Denise Dresser, who works as a professor in Mexico City. “Mexico has never been so threatened and never have we had a government so incompetent.” Twenty-five-year-old protester Ines Carrasco called Trump a “pathetic” “little man,” adding “What concerns me most is that he’s spewing hate.” Alberto Madero, 59, held a sign that said “We will not pay for your [expletive] wall.” According to one Mexican poll, about 80 percent of citizens surveyed said they believe that relations between the two nations will be worse under Trump’s presidency than it was while Barack Obama was president.
