Read colin's argument. nowadays, one often hears complaints that drones can invade people's privacy. but this is not true. flying drones is actually a sport. it requires coordination and technical skills like other sports. in fact, there should be professional drone-flying leagues. if people recognized this sport, they would no longer complain about where and when drone owners flew their drones. is colin's evidence relevant to his claim? yes, because he gives evidence that flying drones is a sport. yes, because it is on the subject of people owning and flying drones. no, because he only gives his own opinion rather than providing evidence. no, because it is about flying drones being a sport, not about privacy issues.
