Am I being censored?

Every so often, I pitch stuff to among others The Telegraph, Guardian, Today Programme and Newsnight, most recently as follows: “No alternative to tax increases to fund social care? Oh yes there is. Tens of billions go on traffic control that fails to keep us safe, contributes to congestion, and maximises emissions. Bizarrely ringfenced, the high-cost traffic control industry escapes scrutiny partly because we’re brainwashed into thinking we need its interventions to keep traffic moving and keep us safe. Nothing could be further from the truth. This piece details the vast potential savings, and manifold other benefits, that system reform would bring.” The editors, some of whom I know by name, don’t even reply, let alone give me column space or airtime. Most have published me in the past. Does non-publication of stonking ideas amount to censorship?
