The bolded statements are
weasel words. You have to do better. I am obviously ignorant of all the cases where people have been called racist because they have used the term "all lives matter". Perhaps you can help me out with my ignorance. People can and have called people all sorts of insulting trash. There are ignorant, bigoted idiots on all sides of political discussions. But people of influence or importance? Help me here...
Find me a quote of a
senior Democrat saying "
Only black lives matter" - Or find me a quote from someone
leading the BLM movement saying "
Only black lives matter' - with context that confirms that it is meant in the way you're implying. Again, find me someone of
importance either in the Democratic party or the BLM movement, saying that someone who says "All lives matter" is racist,
explicitly because they say that phrase and not because they happen to already be racist and say it. Again, full context to confirm the subtle difference.
That way you can help me with my ignorance, and show me that you're not lying, either purposely to create an insincere narrative, or sub-consciously to protect yourself from cognitive dissonance.
