Hi ATCER,
There were lots of little reasons, but the big reason was the "uncontrolled go-around" aspect.

Another issue is the "unqualified participant" issue. Sure, we're all pros, nail the touchdown zone everytime and smoothly make the highspeed, but what about Joe Cessna and his first visit to Big City Metro Airport, or the foriegn carriers where english might be the 2nd language (or 3rd)?

Go-arounds and non-qualified particpants are, indeed, the reasons cited by ALPA for their opposition to LAHSO.
Of course, they disregard the fact that if simultaneous go-arounds on LAHSO runways are a problem, then simultaneous go-arounds on ANY pair of converging runways are a problem-- for instance, if a 17 go-around at PHL is dangerous with traffic on the go off 27R, then that same 17 go-around would be even more dangerous with a go-around on 26, since it's closer and there'll be less time available to deal with the situation. Yet nobody seems to think the 17/26 operation is a problem!
Why not? Because it isn't-- and neither are simultaneous go-arounds on 17 and 27R. To a controller, a go-around is simply a "surprise!" departure-- and separating a go-around from another go-around is no different than separating a go-around from a departure off a conflicting runway (which happens all the time and nobody seems to get upset about it). It's just a non-issue, since go-arounds are always initiated at least a mile (and usually more) from the runway where the conflicting traffic is operating.
As for nonqualified participants, frankly, that's never been a problem either. Before there was LAHSO, there was SOIR (same thing), which has been used with pilots from the student level on up, for almost 40 years-- and a search of the NTSB archives don't find a single accident associated with either LAHSO or SOIR.
There are some legitimate reasons some pilots may dislike LAHSO-- for instance, if insufficient runway is available, or ops are being conducted with unfriendly wind conditions, or the intersection to hold short of is difficult to identify. But the "go-around" and "nonqualified participants" arguments don't hold water-- there's simply no history to back up those claims.
And for those times when a pilot really does have a legitimate gripe, there was always the Nancy Reagan approach-- just say no. Nobody's holding a gun to your head-- if you're uncomfortable with a specific LAHSO operation, then decline it, on a case-by-case basis.
Airports like O'Hare are being strangled by the new LAHSO restrictions-- and for fallacious reasons.
