In fact, "sing happy birthday problem" sounds offensive to me -- this is an incredibly stupid and annoying song. No reason to promote it. Sure firing squad is about killing people, but we already have laws regulating that and in most countries you won't see a sudden mob of gunmen lynching somebody in public places. I have seen no laws about subjecting innocent bystanders in say a restaurant to this horrible "song". I don't even mention the the main victim, who has to sit there with strained smile and suffer through that atrocious repetitive and dumb "singing"...
