Steve-O Says SeaWorld ... F*** You!

Steve-O's been protesting SeaWorld for a long time, and one thing remains clear ... he still hates them.

We got the "Jackass" star at LAX ... he's ecstatic about California outlawing orca breeding and captivity programs, and says he's stoked killer whale shows are coming to an end, too.

Steve-O knows there are still problems, though ... and has some final words of advice for SeaWorld on how they can fix them.
