GC, Milo Yiannopoulos may be a provocateur however I don't think I would place him in the same category as a mafia kingin. Because he supports the right side of politics, takes a humorous look at what makes those of the left tick, seems a little harsh to justify he should be refused a visa, especially when visa's are issued to others who visit this Country to give hate speeches. The Immigration Minister no doubt had pressure placed on him to reverse the original decision, free speech is what it is, if people don't like Milo, simple don't pay the dollars to hear him speak, after all it isn't tax payers money paying for him unlike the public broadcaster.
