Facebook's Mark Zuckerberg criticized the "fearful voices calling for building walls" during his opening remarks at the company's developer conference Tuesday in San Francisco. The social media company's founder and chief executive said the world has become a global community and warned against people and nations trying to isolate themselves — a possible allusion to GOP presidential front-runner Donald Trump, who has heavily pushed a plan to finish building a wall along the Mexican border to limit the influx of immigrants. "We've gone from a world of isolated communities to one global community, and we are all better off for it," Zuckerberg said. "But now, as I look around and I travel around the world, I'm starting to see people and nations turning inward — against this idea of a connected world and community." It's not fearful voices asking for a wall to be built, it's American voices who realize the threat of people who are ISIS and Cartel members flowing in from our Southern border. Obviously Mark Zuckerberg is for the destruction of our nations sovereignty, by willing to allow America to be infiltrated by terrorist and cartel fighters and drug lords. Mark Zuckerberg proving once again to us that he is nothing more then a leftist globalist trying to turn America into an European like nation state. Sorry Zuckerberg but America has laws for people wanting to come to America, and if people don't wanna abide by those laws and values they are not welcome. Hey Zuckerberg realize if it wasn't for America and it's values you wouldn't be the multi billionaire you are today.
