“Censorship is bad” yeah, sure, I agree. But the fact that you still know it’s a curse word means it’s not really censoring anything.
Curse words are so common now that they’ve lost a bit of their oomph. They’re supposed to convey intensity, but they’re used so casually that they’re basically lazy filler.
A strike through line, or a box that doesn’t quite cover, reintroduces a bit of the taboo. This is a bad, naughty word, you shouldn’t be reading it. You know what it is, but attempting to cover it draws attention to the fact that it’s something some people want to cover, which reintroduces some of the oomph.
It’s kinda like sequined pasties at a nudist colony; it turns something that was once taboo, but had since been normalized, back to taboo again to reclaim some of the intensity.
I agree with OP. Anyone remember Adam Sandler’s “Ode to My Car” song, for example? The radio edit is so much funnier than the straight version. Swearing is boring and gauche, but a little bleep over the obvious course word adds a bit of silliness or maybe a hint of taboo depending on the execution.
