Omar Mateen's father,&nbsp;Mir Seddique, spoke to NBC News about the shooting. "This had nothing to do with religion," he told the network.&nbsp;"We were in downtown Miami, Bayside, people were playing music. And he saw two men kissing each other in front of his wife and kid and he got very angry," Seddique told NBC.&nbsp;"They were kissing each other and touching each other and he said, 'Look at that. In front of my son they are doing that.' And then we were in the men's bathroom and men were kissing each other."
