Yusra Khogali in 2016 wrote “white people are a genetic defect of blackness” in a since-deleted Facebook post.

Err, technically correct. Every feature of someone is technically a "defect" of something; it is just that these "defects" aren't always harmful, and sometimes can even be helpful. If having light skin was always harmful, it would have died off long ago.

“White ppl are recessive genetic defects. this is factual,” she said.

My grandmother has very dark skin, while my father (on the same side of the family) has much lighter skin. I myself have light skin, easily able to be interpreted as white, despite being around 25% black. There, is evidence, right in front of my own eyes, that this isn't true at all. Skin colour is determined by many, many genes, not a single dominant/recessive one.

Khogali asserted that white people have a ‘higher concentration of enzyme inhibitors which suppresses melanin production’ adding that ‘melanin is important for a number of things such as strong bones, intelligence, vision and hearing.’

[citation needed] (about what melanin is important for). No, seriously. If there is a study actually claiming this, I want to read it. It sounds interesting.

Khogali also claimed, “melanin directly communicates with cosmic energy.”

Uh, lol? That is a bit… out there. Are we sure this isn't actually just satire people are taking too seriously? Generally this sounds like an intentional mirroring of white supremicist rhetoric to prove how bad it is at this point, and this part is completely not based on any science I know of.

Is this satire? Is there another source for this to get more information? Is this even real? I see no citation yet.

Somehow a tweet I wrote out of anger months before our protest began has become a bigger media story than our protest’s many and profound accomplishments,” Khogali, co-founder of the Toronto chapter of Black Lives Matter, wrote in a Toronto Star column in 2016.

Ah, the classic ad hominem instead of refuting people's actual points! Perhaps they shouldn't do that, but I still think it is somewhat worrying that this co-founder of BLM appears like they may be some kind of black supremicist, given that, well, the group does focus on black lives. That gives a lot more credibility to those who claim it only cares about black lives.

Aha! At the end, the article cites this tweet, which cites this article…

This article cites this image from this page on a site I have never heard of: cnews.conoe.com.

I decided to look up Yusra Khogali, and it seems they don't have a Wikipedia page. Surely that can't be right if they really are the cofounder of BLM? The Post Millenial article also calls her a "Black Lives Matter Toronto co-founder" instead of the co-founder of Black Lives Matter in general. According to Wikipedia:

In 2013, Patrisse Cullors, Alicia Garza, and Opal Tometi formed the Black Lives Matter Network. Alicia Garza described the network as an online platform that existed to provide activists with a shared set of principles and goals. Local Black Lives Matter chapters are asked to commit to the organization's list of guiding principles but operate without a central structure or hierarchy. Alicia Garza has commented that the Network was not interested in "policing who is and who is not part of the movement." Currently, there are approximately 16 Black Lives Matter chapters in the U.S. and Canada.

Notable Black Lives Matter activists include co-founder of the Seattle Black Lives Matter chapter Marissa Johnson, lawyer and president of the Minneapolis chapter of the NAACP Nekima Levy-Pounds.

Yusra Khogali is mentioned nowhere here.

So assuming these quotes are real, it only means that some BLM members are racists, not that all of them are, or even that key ones are.

The loose structure of Black Lives Matter has contributed to confusion in the press and among activists, as actions or statements from chapters or individuals are sometimes attributed to "Black Lives Matter" as a whole.

I think that is what happened here. This article borders on fake news in the way it attributes things, IMO.
