'Oh please! Don't try to turn this into some sort of quasi-racist means to sway your argument, that people who don't agree are racist. Because Britain does have its own society as well, its own values and such. And in its tradition it's not polite to put a statement in invites that you want money as gifts.'
expat, as someone of immigrant stock, I find it staggering that you, also of immigrant stock, think that those with their own cultural heritage should bin it when it comes to weddings so as not to offend the natives.
My family's Greek-Cypriot, but DH's isn't, so in our invitations we just said that we weren't having a wedding list, but we were inviting guests to pin money on us as we danced in accordance with Greek-Cypriot tradition.
We didn't need presents because we had everything we needed, having lived together for a couple of years, so a wedding list would have been pointless, even if more in accordance with British cultural tradition. And it never even occurred to us move our wedding to Cyprus just so that we would avoid offending the delicate sensibilities of our non-Cypriot guests.
Most people pinned money, some gave cheques in cards, but only three people gave us presents (a mirror that's actually quite nice and is hanging in our hallway now, a hideous wine coaster that went to Oxfam, and a silver-plated plaque in red velvet-lined box with our names (incorrectly spelled) and the date of our wedding, which is languishing in the loft because we can't think what to do with it).
But whether it's the cultural norm to request money or not, I don't know why so many of you are so het up about it, or about wedding lists, and even silly poems. It's the bride and groom's day, not yours, and as long as they're not asking you to pay for your meal and drinks, or the wedding list isn't from a hideously expensive shop, then I just don't see what the problem is.
However, I do think that asking for any presents or money for a fourth wedding is a bit off so, OP, YABU to be annoyed about it. I'd still go to the wedding, and I would give money (although not very much), but in the form of vouchers for a high street shop.
