Why does the Bible say nothing about Pedophilia?

Pedophilia is a form of fornication.

The Bible declares that all forms of fornication are wrong. (1 Corinthias 6:9, 10)

It does. Pedophilia is another form of fornication. Because fornication is any sexual contact outside of marriage. And, fornication is a sin (1 Corinthians 5:12).

I don't know but it is evil in any case.

Webster’s Ninth New Collegiate Dictionary defines “pedophilia” as “sexual perversion in which children are the preferred sexual object.” Aspects of this practice are condemned at Deuteronomy 23:17, 18.

it doesn't mention running STOP signs either ........................................

The Bible says that fornicators who do not repent will be cast into the lake of fire. Revelation 21: 8

Fornication is every kind of ilicit sexual relation

Pedophilia is also. Example: Is it normal to suck an orange or any other fruit that is green? Therefore, it is sin.

doesn't say anything abut abortion either. Or being a lesbian. But you can "interpret" it to say things about those.

because they probably promoted it or it was not an issue previously

Pedophilia is a form of fornication.

The Bible declares that all forms of fornication are wrong. (1 Corinthias 6:9, 10)

One can only guess that the human authors of the bible were OK with it.
