Ganking and highsec PVP is comparatively very weak compared to it’s state throughout the game’s history. HP of ships like barges and freighters are up, and with sub prices alt numbers are down.
There’s no conclusive evidence that the actual act of ganking harms new player experience - quite the opposite as CCP state their data shows that losing ships to other players tends to improve player retention.
The real thing one sees in Rookie Help all the time that drives away new players is scaremongering by snivelling cowards that massively overrate the threat of ganking to both new and experienced players.

Your arguments are of no value because you refuse to provide evidence for any of your claims.
