Someone gets riled up at me and all of a sudden they speak for everyone else.

And it's really everyone else. Not "just a few people" or "some people."

Example:

No wonder no one likes you
This is why no one on IA can stand you

Lolol.

Instead of the truthful way to put it:

I can see why a few people don't like you
This is the reason why some people on IA can't stand you

To those of you who do this, please explain your thought processes to come up with this delusional state of mind. Later, QD.
