Etymology is really interesting. And the meaning of words can change and new meanings can be associated over time. The word computer dates back to the 17th century referring to a person who calculates.[0] I don't think this is the meaning most people intend when using the word computer today.

I'm not condoning the use of hateful language or threats. I just find your example problematic.
