If you believe that concern and discussion are material acts in themselves, then you have a somewhat primitive view of what constitutes human behavior - as if ideas have never shaped history. This isn't the issue of the day any more than climate change, non-proliferation, homophobia, sexism, greed, or questions of identity are the issues of the day, which is to say, they all are.
We get it, how dare we burden you, and your important personal affairs tending to your accounts and your reputation in the United Kingdom, with questions concerning global health, global peace, global justice. What trifles they are, after all. Such lofty ideals.
Don't forget that the United Kingdom is a province of the loftiest kingdom, the Kingdom of Heaven, and no one through any protestations of self-righteous apathy can successfully renounce their citizenship. The tax will be collected whether you can afford to pay it or not, so you'd best do what you can now to save up, lest you find yourself on the wrong side of natural law.
What I find interesting about you is that you seem to expend, at minimum, a significant fraction of your moral, intellectual, and rhetorical resources and energies on these supposedly irrelevant global issues as I do, all in the name of insisting you shouldn't have to. How else did you end up opening a thread on a topic you supposedly don't care about?
Or is your interest more toward being petty and confounding myself and others like me who do care? Because if that is the object of the concern you demonstrably display here, rather than the issues themselves, I say your personal affairs need some re-prioritizing.
Of course, "tout comprendre, c'est tout pardonner," and I assume that there is a perfectly human explanation for this apparently contradictory, or worse, apparently mean-spirited behavior, but since you have so far not shared such an explanation with us, we are left to wonder.
I have been the object of critique and ridicule on this website for being willing to provide personal background and shed some light on my personal motivations for my lifestyle and ideas, but I do not regret sharing it, because I know that for cooler heads who also happen to disagree, it humanizes me in a way even my words about the brotherhood of humanity cannot.
And when I wished your country luck with Ebola, I was sincere, just as I wish all the world luck against the upcoming global plague, whenever it strikes us - for it is a when, and not an if.
