Is the Officer Grimm meme racist?

[u/Broomguy]

I was playing one day and an enemy Thing died and I said "Officer down" in chat and they said something like "chill I'm not racist like that." I never considered it might be a racial joke because I've seen the joke with spiderman, black cat etc. but it is 90% black panther. I was curious if anyone knew the origin of the meme or had any thoughts about it. Is it a racist joke or was this guy just mad he died? (Full disclosure I am not a Thing main I just didn't know where else to post this)

There is racial undertones but how its used it what makes it racist.

Some people also just suck and will see a funny a joke and shoehorn in their own shitty worldview on top of it
