You must consider the source when evaluating any words as the basis of a philosophy you would defend.
There are gradations of sins, from a “white lie” told to another intended for their protection, to intentional genocide based on some identifiable aspect of a group.
What Malcolm X did was more of the latter than the former,
particularly when he characterized persons he never conversed with as “white devils” for the purpose of recruiting and retaining power from individuals associated with the Nation of Islam.
Before Malcolm X was in a position to make those statements publicly, he was a criminal and a gay prostitute, both of which are professions that are contrary to the Christian morality you write of. However, they are consistent with prison-based recruitment by the Nation of Islam.
Knowing that, is this the sort of person whose words are to be defended here? I argue: Absolutely not!
Or, to simplify what I’m saying, you can also google the Islamic practice of “taqiyya” (religious tenet of lying to non-Muslims)
By your own insisted-upon standards, the lack of proof of your personal moral purity renders your words not only garbage, but possiblly dangerous poison to the soul that I would never want heard in my own house.
Please note those are the exact standards you declared necessary to evaluate any person's teachings, positions, declarations or even truth itself.
As you have not been forthcoming with proof of your moral purity for the entirety of your life, I reject your words, based on your own declared evalutaion system, as lacking proof of this necessary purity. Per your standards, it doesn't matter what you say - it matters who you are, and who you've been every moment of your life, and if you've ever sinned. Furthermore, failure to provide said proof after you have been challenged to meet your own standards suggests tha you cannot provide such proof, and that you are hiding some vile moral failure you made at some point in your life. Of course, per your standards, failure to be perfect at any time, means anything whatsoever you say now about any subject is - by definition - untrue, poisonous, vile and something that should never be listened to, considered, studied or brought into anyone's home.
Therefore, until you provide proof of your own moral purity, for the entire extent of your life, I dismiss your words as meaningless at best - and morally dangerous at worst.
Per YOUR standards.
Bye.
