I think these things have died a death for most people, and here's my theory on why.
Prior to social media, people would have to ask you f2f and that would not only be awkward to say no to, it would be very infrequent and limited to people you had immediate contact with.
Over the past 20 years we've gone through various levels of enhanced mithering. It started with round robin emails. Then it was posts on social media. Now it's relentless. Not to mention charities accosting us on every street corner, plus regularly cold calling and doorstepping homes.
Now that everything is online, it's incredibly easy to hold out the begging bowl for donations for everything. Most of these are well intentioned, I might add. The whole concept has died through overexposure - because when you're asked everything 5 minutes it becomes tiresome. It's also become easier to ignore as it's out there in the ether.
A second factor is a greater awareness of the many charity scandals, frauds or abuse like that bloody Captain Tom family.
Not to mention - the numerous non-fraudulent rackets people have shared where most of the money goes to the sodding activity (like the parachute jump) with the leftover bit going to charity.
Having said all of this, although I voted YABU, I really feel for your poor husband, who is stepping up and getting short shrift. 😔
None of the above is personally his or your fault, but sadly even the generous people i know will not usually give outside of immediate family.
As for charities, I think they have collectively shot the golden goose in the free for all. It's very sad, because there are so many good charities that do excellent work. Typically they are all fighting in the same marketplace and if one becomes more aggressive, they all have to follow suit.
They're now competing with each other, with pseudo-charities like private schools, pseudo-fund-raising like parachute jumps, dubious benefits like trips to Africa, and downwards the slippery slope to fake gofundme campaigns, attention-seeking celebs and finally just plain fraud.
I fear that just like everything online, genuine people are at a disadvantage, getting drowned out by the cacophony of people who want to prose open your wallet. 😔
I hope that at least makes it feel less personal. Because its not.
