Jackson is so supportive and encouraging (not to mention thoughtful and considerate) yet people always find the most petty reasons to hate him. Wow, make it obvious you're just trying to use any excuse not to actually learn about him. Today is Mark's birthday and he went out to buy him a cake with his own money. On their first Weekly Idol appearance, despite the hosts telling him to come out and dance, he didn't (and risked coming off as rude) because he wanted Yugyeom to have the opportunity to show off his dancing on his own. If the members get embarrassed or having a hard time, he always does something to encourage them, like with Mark @9:27. And the list goes on. His member's only speak about him with nothing but positive and loving comments, like how they say he's the one that always tries his hardest to keep the mood light and brings all his energy when the other members are having a hard time in order to cheer them up. He's a moodmaker and they're not just saying it for no reason. Even when you look at their pictures, you can tell he's the most affectionate with every member. His "bluffing" is just a front and it's obvious. So stop confusing his lighthearted and playful nature as "childish and annoying", because he's anything BUT that, and using it as a device to hate on him.
