What is wrong with people these days?

I used a term, and a guy immediately got triggered because of an exception, that I don't even see as a part of the term anyway.

So, I explain to him carefully, that I see the term differently....... and he keeps on looping on the exception.

Then I tell him, that the exception is NOT my opinion....

And he again talks about the exception.

What kind of a brain hammerage is that? Why is he arguing, when I outright said, that it isn't my opinion in the first place?
