Do you see any irony in "older people" blanket term whilst nailing your non-racist credentials out there? Not enough conviction to call them on it in person. Or even have a civilised debate with them?
I don't think it's better to hoik and gasp and point with others in an orgy of outrage that the older generation have different life experiences to you.
Where I come from, there are places that white people rarely go. If they do see someone different (my DH) people point, exclaim, comment. To them, it's something totally out of the ordinary. Would you slam then as "ignorant and racist?"
They haven't travelled, are not sophisticated people but they have good hearts.
Many older people in this country haven't travelled much, and they aren't, despite what Londoners tell them, exposed to 'multicultural Britain' on a daily basis.
Rather than the default liberal hypocrisy stance so beloved here, why not engage, without name calling, fainting or hyperbole?
Do you genuinely not see the irony in berating total strangers, based on a tiny snapshot, for not sharing your supposed broad-minded philosophies.
The jackboot is still about in Britain it's just worn by different people now.
