PvE servers are for the week players out there.
So you would say PVPers are the weekend warriors? Eh? Eeeeeeh?
What you say was once true back in the EQ and UO days. But in modern MMO's where there are Battlegrounds which offer rewards for PVPing, PVP servers tend to be where the weak like to hang out to try and grief lowbies. I'll likely still play on a PVP server out of years of habit...but I don't expect to see to much world PVP after a few months.
