1Cor 15:33 – Be not deceived: evil communications corrupt good manners.
You can turn this around and say it another way:
“If you think you can listen to, read, or watch evil communcations and not be effected, you are deceived.”
Just turn on the television, listen to the radio, or flip through a magazine at the supermarket. Within in 5 minutes you will be exposed to more perversity and obscenity that most folks might have been exposed to in an entire lifetime not 50 years ago.
All around us, every form of media seeks to push the limits and go to another level of extreme in order to get our attention. The reason they have to keep going to extremes to get our attention, is that we get desensitized to what we are repeatedly exposed to. A side effect is that once they sink to a deeper level of depravity or go to another level of extreme, we become desensitized to what once we had an emotional reaction to.
Desensitized simply means that we are no longer sensitive to it, that it no longer provokes the emotional reaction it once did.
Desensitized DOES NOT mean that it no longer has an impact on us. To the contrary, it merely means that our guard is now totally ineffective, and we now let these media messages come pouring into our minds without any check or balance.
Things that were once abhorrent are now the subject of sitcoms that we blithely laugh along with the prerecorded audence to. All the while our minds are being conditioned to accept and even support things that are an abomination before God.
Rom 12:9 Let love be without dissimulation. Abhor that which is evil; cleave to that which is good.
Isa 5:20 Woe unto them that call evil good, and good evil; that put darkness for light, and light for darkness; that put bitter for sweet, and sweet for bitter!
