Neo notes a phenomenon that may be familiar to some of you:

We’ve previously mentioned bizarrely emphatic and incongruous outbursts, the relevance of which to ongoing, often mundane conversations was hard to fathom, and which seemed driven by a compulsion to signal some imagined piety or status. A more subtle and common example occurred in January, when the family headed out to a Burns Night dinner at a restaurant adjacent to the university. Before the food appeared, we were treated to a brief poetry reading courtesy of a local academic. I was tempted to roll my eyes at the prospect, but he did get the crowd in good spirits. Until a poem about food and good company was somehow given, as he put it, “a political edge.” And so, we endured a contrived reference to Brexit – implicitly very bad – and a pointed nod across the ocean to a certain president, who we were encouraged to imagine naked.

At the time, I was struck by the presumption – the belief that everyone present would naturally agree – that opposition to Brexit and a disdain of Trump were things we, the customers, would without doubt have in common. That the poem’s sentiment of friendship and community was being soured by divisive smugness escaped our local academic, whose need to let us know how leftwing he is was apparently paramount. The subtext was hard to miss: “This is a fashionable restaurant and its customers, being fashionable, will obviously hold left-of-centre views, especially regarding Brexit and Trump, both of which they should disdain and wish to be seen disdaining by their left-of-centre peers.” And when you’re out to enjoy a fancy meal with friends and family, this is an odd sentiment to encounter from someone you don’t know and whose ostensible job is to make you feel welcome.

It wouldn’t generally occur to me to shoehorn politics into an otherwise routine exchange, or into a gathering with strangers, or to presume the emphatic political agreement of random restaurant customers. It seems… rude. By which I mean parochial, selfish and an imposition – insofar as others may feel obliged to quietly endure irritating sermons, insults and condescension in order to avoid causing a scene and derailing the entire evening. The analogy that comes to mind is of inviting the new neighbours round for coffee and then, just before you hand over the cups to these people you’ve only just met, issuing a lengthy, self-satisfied proclamation on the merits of mass immigration, high taxes and lenient sentencing. And then expecting nodding and applause, rather than polite bewilderment.

Update, via the comments. Two additional illustrations of the same phenomenon:
