By all means knock yourself out. Some of us have been carrying on the conversation for a decade or more. More like 2 decades for me personally, and I'm exhausted. I can barely even read half the posts in this thread because it saps me of my life force. If you want to continue to do so, that's good. We need more educated, illuminated people ready to try to help illuminate others when possible. Just understand (1) if you're not woke yourself, you're a detriment to the cause and (2) your wisdom and experiences will usually go in one ear and out the other.
Oh, and never argue with anyone on Facebook or comments sections of anything. That's where the author of the OP went wrong. Helping people get to a place of better understanding requires an audience capable of considering, entertaining and maybe accepting that their perspective may have been incomplete on certain topics that are essential to the conversation. Facebookers/news commenters/ youtube commenters are not interested in truth; they're interested in being hateful and anonymous.
For example, if someone asks you why black people are poor and usually live in ghettos and urban areas and you don't know enough about
white flight,
gentrification,
housing discrimination,
the long history of denied home ownership, or
how the history of wealth inequality for people of color related to ownership of things impacts everything from present opportunities to future ones (as well as the history of all of the above), you can't help wake anyone up. You need to go spend some more time in the library yourself. And that's just one angle on one topic among hundreds. The same topic can be tackled with examining the impact of slavery on the black family, the creation of urban zones without opportunity for upwards mobility, inaccessible higher education, self-hate and their strength of popular culture, so on and so forth. All of which tie into the matter. All part of the complex web of things that act upon and interact with the lives and times of all people of color.
As you said earlier, being black doesn't make you an authority on any of the issues being discussed. Or perhaps better stated, it doesn't give you the innate ability to be able to discuss these issues with the level of depth and complexity they require to wake someone else up. But it does mean you have enough skin in the game to educate yourself well and impart some of that on others as many of us here have done over the years.
You'll have to pardon our reluctance to continue doing so. We've done our part to help when we didn't have to. If you're capable of stepping up and doing more than deriding what you feel other black folk aren't doing enough of or calling on whataboutisms to frame your arguments against black folk, then step up and do so. If this was your audition, consider me both uninspired and unimpressed so far.
