A day after hundreds of thousands of young people took to the streets to call for gun control, an old man used his bully pulpit to urge them to keep shouting, reports Reuters. Speaking at his Palm Sunday Mass, 81-year-old Pope Francis warned that "the temptation to silence young people has always existed," along with ways "to sedate them, to keep them from getting involved, to make their dreams flat and dreary, petty and plaintive." But, reports the AP, he told young people that "It is up to you not to keep quiet. Even if others keep quiet, if we older people and leaders, some corrupt, keep quiet, if the whole world keeps quiet and loses its joy, I ask you: Will you cry out?" The response from the crowd: "Yes!" (More Pope Francis stories.)
