The original AITA post is locked, otherwise I'd post this there.

* Originall OP chose to use a click-bait title

* But in his words, the girl was "looking at vibrators on Amazon".

* He confiscated the laptop.

* The wife gave the laptop back to the daughter.

* Nowhere does he say - apart from the click-bait title - that the wife is encouraging the daughter to buy sex toys online. The wife was instrumental in getting the laptop back to the girl.

* The girl was looking. Looking doesn't mean buying. She was curious. It's the Dad that assumed she was buying. 

* Incidentally - buying with what? Does she have a credit card? PayPal? 

* And now we have another post - from NewOP - with more click-baity rhetoric.

I supect both posts originate as a manifestation of some degree of inadequacy on the part of the OPs.

A child was curious, she followed her curiosity, OriginalOP projected onto the situation and banished the computer. He handled it poorly. 

Girl wanted her computer back, Mom gave it. 

Girl didn't say she wanted it back to buy sex toys. 

Mom didn't say she was giving the computer back so the girl could buy sex toys. 

But apparently, the only reason a 12 year old would want her computer back is to buy sex toys.

All of that bollocks came from OriginalOP. And now NewOP.

TL:DR Looking is not buying. Stop projecting your male sexual insecurities onto the women in your life.
