I don't want to use parsers

I worry that even if DPS/Total Damage values were shown to under-performing players, they would still put just as much effort in as they usually do. Sure there will be those who try harder when they found out their performance but what happens to those who don't use the information? Would you kick them for it? My question is what will the community do to those people?

This might sound cold, but if a player knows that they have issues that are affecting their parties and flat-out refuses to do anything about them, am I supposed to care what the community will do to them?

I don't harass such players; I simply avoid them once I identify them. If someone is performing so poorly that they are holding back 7 other people, and if they are both aware that they have a problem and unwilling to "try harder," they need to go.
