This is honestly one of the reasons I don't oppose spanking (within reason). It's like veganism - this kind of conversation never gets settled, never goes away, because there's always some nuts that's going to take the extreme position that you're the epitome of evil for doing whatever you do, when that's honestly always been done by humans for thousands of years.
You're the epitome of evil for eating meat...
You're the epitome of evil for harvesting crops using machines that kill little baby bunnies...
You're the epitome of evil for eating food that little baby bunnies would have eaten if it wasn't for you being such a filthy hungry and greedy human.
And people treat them seriously, like people worthy of debating. It's all so tiresome.
Now you're telling me that there are people saying that time-outs are evil? Next thing you know, those "time-ins" are going to be considered evil because it's forcing the violence of speech on poor little children.
