So, I read the entire thread
One: Comparing soap in the mouth to oral rape is just baffling. I've worked with rape victims. It is NOT the same.
Two: Yes, soap in the mouth in the UK can be classed as abuse. Will SS take your kid for doing it once? Nope, probably not. Over the long term? Yeah, there will most likely be some action.
Three: I (as in me) would not do it. I didn't have it done to me and it doesn't solve anything really. There are better ways to discipline your children.
Four: Why would people say they had it done to them and are okay, but wouldn't do it to their children? What's the point of defending your parents' practices to the high heavens? My parents did a lot of things I don't agree with. Were they bad parents? Hell no. Were they guided by antiquated practices? Yeah, most likely.
