creepy middle-aged man in starbucks?

I know he's a UTA employee, but he tends to sit around in the Starbucks and swear really loudly about "fucking" Obamas and being really angry about wherever Trump was sitting in whatever meeting he was in. He also seems to be the really passionate internet commentators, typing furiously replying to an article on facebook.

​

he seems like a really angry man, he keeps swearing loudly and i'm not sure if the UTA authorities should know about him?
