It’s not an ‘easy insult’. Just look at these threads. The same things come up again and again, a complete lack of understanding of how government works, the difference between the PM and an elected ceremonial HoS (see predictable comments on ‘I wouldn’t like a President BoJo!’) the difference between an elected HoS (who might be called a ‘president’ or something else) as a largely ceremonial role and countries in which the president has considerable executive power (eg the US — cue predictable ‘You wouldn’t want Trump as an elected HoS, would you?’, with an air of cleverness), why an elected HoS would in no way need to be a politician (no particular reason why Judi Dench or David Attenborough shouldn’t be candidates), a misunderstanding of tourist revenue requiring a regnant monarch to pull in foreigners, despite Versailles doing perfectly nicely despite the guillotine), and how inexpensive an elected HoS is in other countries ( inIreland the presidential salary is pegged to the top civil servant scale, for instance, plus the use of a house, transport, security), how Andrew or Harry aren’t some kind of anomalies, but examples of what happens when you have a hereditary monarchy — you don’t get to choose, you get whoever is next in line, regardless of whether that’s a dutiful drone who spends a lengthy reign never stepping out of line, a dimwit playboy, a Nazi sympathiser or someone who knowingly consorted with a paedophile.
What’s depressing, but perhaps more understandable is that so many pro-royal people on here don’t trust the electorate or the democratic process, though this predates Brexit.
There are no reasons that stand up to scrutiny for wanting the monarchy to continue in its present form in 2023. People may as well admit to themselves that they like the tabloid soap opera of Harry, William and co, Charles and the tampon, Saint Diana, and that they like posh frocks, marching, tiaras and state coaches, as a distraction, like a long running tv show, or that it illogically makes them feel there’s something unbroken about Brexit Britain, that they believe foreigners still envy.
