This is a meme in Christian apologetic circles because non-Christians always think it's a big own when it is really just a demonstration of a lack of understanding of what Christianity is actually about -- Redemption.
It being a meme doesn't mean there isn't a reason for the argument. Redemption from what? Whatever it is, God had control over it happening. Why did it happen? He is trivially capable of creating a universe where there is no need to be redeemed. Why is one where redemption required the one he chose to create? Dismissing something as just being a meme does not actually answer the question.
God does not play by your rules. The struggles we face on Earth (often of our own creation) are for our salvation. This is what the bible and church tradition teaches.
The point is, God knew we would create the struggles. Is he omniscient? He knew it would happen. Is he omnipotent? He could have created a situation where it doesn't happen. Is he benevolent? He wouldn't want it to happen.
Yes, this is what the church teaches. I'm well aware. Does it make sense?
