You need 2 understand the difference between corrective corporal punishment and child abuse.  A board is an object you shouldn't use to hit a kid & I'm sorry your parents abused you.  

But a house shoe against my kids behind taught them not to do a lot of crap!  They were taught young enough that they didn't and don't need spankings at an older age.  My kids don't lie to me, they get all As n Bs and they have lots of after school curricular activities they engage in to better themselves.  They don't hang out with negative kids, no matter how much peer pressure surrounds them.  They stick up for themselves, they don't let people push them around, they don't let kids pressure them into sex, drugs, or vandalism.  They don't have social media accounts and they have phones that are strictly monitored but from what I've seen are used responsibly and my kids grew up in a home where you got spanked if you acted out.  So just because it doesn't fit your model of parenting doesn't make it wrong
