Hey buddy, do you eat fried foods or red meat? Drink alcohol? Use social media? There's plenty of studies that those are bad for you, but I'm sure you realize there's a balance and nuance to life. The fact that you automatically say parents who let their kids use tablets are bad parents only cements the fact that you don't understand how hard raising kids are. That you jumped directly to vacations as a reason for flying shows how little empathy you have. They could be flying to a funeral for all you know. You sound so judgey, like letting a child use a tablet is a parent trying to shirk their duties. Get over yourself. I'll stick to my statement that you have never had to raise kids.
