Needless to say, attempting to ban the game from my life was unsuccessful, even with scorched earth policies like physically cutting internet cables. Meanwhile, I firmly credit my time on this game as the kindling to my career as a developer. A point which (along with making more at 23 than he did at 45) I take great pleasure in reminding my father of whenever the opportunity arises.
Here's to hoping your kid grows up and finds an annoying and creative way to say "I was right, you were wrong, check out this pile of cash I got"
We'll see how it works out, but I'm hopeful.
It seems that your entire decision to ban Minecraft stems from your impression that they're "too obsessed" with it and that they shouldn't be spending so much time on something that they are clearly passionate about (studies and research show that passion generates the best workers and innovators!)...
I raise my children based on my own judgments of what's best for them. And I use my own God-given intelligence and experience to form those judgments.
So no, I will not agree with you. If you do not agree to disagree, then that's your choice. But disagreement doesn't require both parties' content.
So you refuse to acknowledge that you might be lacking in knowledge and experience in some critical aspects of your childrens' education. And/or you refuse to accept that the conclusions you reach with your limited knowledge, alone, one single human out of billions, might be erroneous and cause harm to your children. And/or you refuse to accept that there might be others out there with more knowledge and experience than you on certain topics. And/or you think God will make everything okay just because you have faith, and the fact that people get raped and killed every day despite their faith does not sway you.
I think that, right there, is the source of your problems.
I pity your children for having you for a parent. For having someone like you be in control of their lives.
