i feel like many of the things id be doing on facebook that are “wrong” i already do
not saying you should put yourself in a situation where you will do the wrong thing
No no no no no. It doesn’t make a difference where your level is or where you think your level is; joining Facebook for the wrong reasons is still wrong. Being on that level doesn’t somehow neutralize the wrongness of it. So you feel justified in dragging yourself deeper? That’s not good judgment. Being where you are is not a justification for doing more wrong things.
because ive heard some pretty bad things which i cant imagine are true
No, they probably were. The point is that they won’t necessarily be true in every case – but that the tendency toward such things might be too strong to bank on that probability alone.
