Biafra's objections specifically stem from the song's placement in the film, in a rape scene:
The scene is actually in the "Planet Terror" film directed by Rodriguez. Tarantino himself is pointing a gun at a disabled amputee woman's head yelling "Dance, Bitch!" as the Nouvelle Vague cover of "Too Drunk to Fuck" plays from a boombox. The terrified woman later "wins" by killing Tarantino, but that excuse does not rescue this at all. I wrote every note of that song and this is not what it was meant for.
Some people will do anything for money. I can't help but think back to how prudish Klaus Flouride was when he objected to H.R. Giger's painting on the "Frankenchrist" poster, saying he couldn't bear to show it to his parents. I'd sure love to be a fly on the wall when he tries to explain putting a song in a rape scene for money to his teenage daughter.
Jello and his former bandmates have frequently sparred in the press in the years since the lawsuits which allowed three quarters of the band to tour with him.
Note: As Jello's message contains a possible "spoiler" you will need to highlight the note to see what was said.
