I think the "misunderstanding" is on your part and I'm not convinced it is one at all, I think it's a deliberate deflection. I'm refusing to accept the tangent you already went off on. You were asking the poster whether they condemned incident A when they posted about people not condemning incident B and I've asked why they should have to answer to you about it. They have a post history where they clearly have condemned it in the past and there is no reason why they should have to caveat their opinion to appease you regardless.
From this point on I expect you to question everybody about their position on every aspect of a situation if they don't explicitly cover it in their post, otherwise my spidey senses of an ulterior motive and racist undertones will start tingling again.
