I think the black community in general is very ambivalent about Thomas. They are proud of his achievements as only the second black person to serve on the Supreme Court, but do not agree with many of his racially harmful positions (redress of grievances and prejudice against black persons). I think that is why you don't see BLM activists specifically addressing his role in harming the black community through both legislative negation and his segregationist and racist views. In general, the Supreme Court is not what stands between black folk and true equality of opportunity in this country. It's mostly legislation and boots on the ground racism, particularly the latter in my personal experience. All of us white folk, no matter how well intentioned, are somewhat tainted by hundreds of years of racist culture and thinking. It is only now that we are removing monuments to traitors and racists, renaming both government and private institutions to get rid of the names of malignant racists like John Calhoun (former Vice President) and relatively more benign racists like Robert E. Lee.
As for the Harry Hieke thing and the OG Forum, it's tribalism. The OGF, like the MTJ, formed amongst those who didn't like or were banned from the OGR Forum. Like here, there's lots of bad karma, bitterness, whining and special pleading. The ostensible leader of the OGR, Brian Vaill, has some big chips on his shoulders and these come through when someone crosses him, as Harry apparently did, intentionally or not. Like most of us, he has feet of clay but pretends to be the reincarnation of George Washington, Abraham Lincoln and Babe Ruth.

My experience with Mr. Muffin (Steve Nelson), Harry Hieke, or those of people I know is uniformly fair and reasonable, so I think Brian needs to take some humility pills and restrain his self-justifying rants from time to time. More chill, less ill will.
