With all due respect, sir, there's two things going on here.
The mockery's because this so nicely illustrates the primitive attitude that by merely
suggesting something, one's a "good" person, a virtuous person.
I call it 'Skippyism," after the NYC_SKP primitive, who's notorious for saying nice things but avoiding actually
doing them. He's a nice guy, because cheap sentiments trump actually doing something.
We saw this with the life and career of the late Vast Teddy--and I'm sure future historians will take note of this aspect of his character--who was popularly perceived by many of the public as being a "generous, giving, magnanimous politician."
It's easier than strawberries-and-cream, to be generous with
other people's money.
But that's no virtue, because virtue demands sacrifice, that one actually do something oneself.

The second thing is, I've known a lot of people like you, sir, in real life, and I quite reasonably suspect you've done others more kindnesses, been more charitable and compassionate and giving, than the whole of Skins's island's ever done.
But you don't
advertise it, and so in the primitive mind-set, you don't do it.
God knows you do, and obviously that's enough for you.
Kudos for your Christian conscience; it's laudatory, and well worthy of emulation.
