Many feel it is their duty to meddle in others lives. To them it is "helping others right", "doing good" and doing "the Lord's work". They're called missionaries, whether by themselves or their churches or by their comrades. They see others violating what they themselves consider to be the values and ethos of civilization - most typically their personal concept of what is euphemistically called "Christian civilization" (WTF is that, anyway?) - and cannot resist sticking their pointy little noses into the lives and affairs of others. Whether or not the activities of these other people actually affect them directly - or even indirectly - is of course the entire point of this perpetual debate on morality.
I suppose the very first question that pops into my head at this point is "WTF has my morality got to do with you?".
I could also ask these self-appointed crusaders WTF my sexuality, sex-life, choice of a partner, their gender, and who I choose to marry and what I do with them in the privacy of my bedroom has to do with them?
They meddle in the affairs of others, spreading news nobody needs to hear or cares about - and then act all "persecuted" and offended when their noses get knocked out of joint by the all too predictable slamming of a door.
