I usually know Fox News Brain when I see it. DQ may not have it, but may have something else.
I think it's called "trying to give some people in my community the benefit of the doubt before I condemn them as racists"
Giving people the benefit of the doubt provides shelter for people to say ignorant crap. Sometimes things are non starters, if you are making the choice to tie the phrase black lives matter to some nebulous organization that may or may not believe in things you may or may not understand, that's intentional, especially if you make the choice to offer that opinion to someone else without researching, with an open mind, what it is that you're talking about.
The only two things the racists oppose when it comes to black lives matter is the marxism thing, when you Google the word marxism, this is on the page, you literally don't even have to visit another website "To define Marxism in simple terms, it's a political and economic theory where a society has no classes. Every person within the society works for a common good, and class struggle is theoretically gone." Is that something worth dismissing literally anyone over? The only other thing is the "destruction of the nuclear family" talking point and that only takes one click to see that isn't related to getting rid of fathers, but emphasizing the community or village in raising our children. Again, not remotely objectionable.
If you can't be bothered to research or contextualize this thing you so vehemently oppose, what that tells me is that you think so little about black lives actually mattering that you can't spend 10 minutes learning about it. You can try to put it in whatever light you want to but that is 100%, inextricably tied to race.
I'd take it a step further and say that if you know these things and aren't repeating them every time this subject comes up, you are enabling racism. If there was a standing narrative that white people haven't earned anything honorably in the history of the world, you'd damn sure try to bust that narrative.
