I wish the Guardian would stop using “we” and “us” to mean “some people” (How Covid killed the one-night stand – and made us all kinkier, 27 January). The chances that we are all kinkier are nil, as many of us weren’t kinky in the first place and mostly, I imagine, still aren’t. Also, there’s a heading about “our obsession with fish oil”. I’m so obsessed with fish oil that I can’t recall when I last even thought about it; surely I’m not the only one.Mark MillerKendal, Cumbria

Thomas Zimmer ignores the fact that the United States is a republic, not a democracy (The US Senate presents a long-term threat to US democracy, 24 January). Americans pledge allegiance to “this republic”, not to this democracy. The US Senate and the electoral college are bulwarks against being ruled by the guillotine of democracy – a fact made clear by French history.Richard Sherman Margate, Florida, US

Adrian Chiles might write of poetic expressions to describe players from West Bromwich Albion (Let’s not say ‘pip pip’ to our most poetic expressions!, 27 January), but that same team beat my own beloved Peterborough United 3-0 last Saturday, leading to much self-flagellation and chants of “We’re so shit it’s unbelievable”.Toby Wood Peterborough
