Not at all. But all men are flawed.
Same for women. But we don't nag.
We are all flawed in some way or another. I've become old enough to be able to admit that the good that a man does CAN be viewed separately from his private deceit of the extra-marital variety, for example.
The real problem, in my view, that the left has about disclosing King's extracurricular activities is that they feed directly into certain, shall we say (then) long-held stereotypes about black men.
Switching topics, black America ought to have been OUTRAGED about the "First Black President" Bull about Klintoon. Why? Well (besides the obvious), let's look at the 'Toon: a skirt-chasing, lying, drug using, over-sexed rapist, perjurer, organized criminal, liar and grifter. (I may have forgotten a few things, I know.)
It don't take a genius to see that much of said behavior fits 'like a glove' into some of the oldest, vilest stereotypes about black men. Oh irony of ironies. But since liberalism has trumped 'blackness' within the LIBERAL black American community, this point was either lost on (or ignored by) the likes of Tony whats-er-name who first came up with this ludicrous moniker for the 'Toon.
