How would an optional, official parser be toxic?

Why do people say this? WoW doesn't have a parser out of the box, you gotta go install it from a third party site, just like with FF, and in WoW I've literally never seen anyone get heckled for their DPS.

They weren't exactly heckled for it, but I was in a Heroic raid last week where we had to remove a DPS who was doing less damage than the tanks. Like... way less damage. Which is precisely why I want an official parser in XIV too, so there's no song and dance around trying to find out who's dragging down the rest of the group. Personal parsers and ratings at the end of the run are useless for in-the-now progression and overall.

It is only because you are not in an officer chat.
Also, even WoW does not have an official parser out of the box, why S/E need to offer one?

Why shouldn't it? I've never seen a legitimate argument against parsers. It always boils down to "someone might use it to be mean" which is a poor reason not to have a helpful tool. Some people may use it to be a dick, but they're going to find a way to be a dick regardless.
