This post by Popehat could almost serve as a manifesto for this blog. It’s framed in the context of American politics, but summarises many major points of self-serving tribalism and othering which can be seen in every kind of discussion imaginable.
They are constantly saying vile, racist and sexist, and threatening things about Us. That’s unacceptable. To make things worse, because They don’t understand humor, satire, parody, or context, and because They are willing to misconstrue things for political profit, They are constantly and unreasonably whining about Us of saying allegedly vile, racist, sexist, and threatening things about them.
What he’s not bluntly and dully spelling out, of course, is that there really is no “Us” and “Them”. There are no “Others”. But breaking that habit of thought – the habit by which we tend to make excuses for ourselves and cast our own group in a favourable light, while condemning the “enemy” at every opportunity and granting them no such leniency – is difficult and unnatural, and requires a good deal more reflection, study, and humility than many of us are capable of or inclined towards.
