This guy is only making himself look foolish. Stop gobbling all of her bait! Greta has nothing to lose, but this fellow has his ego to maintain. He should have played the ‘Adult’ in the conversation, instead, he acts like somebody in Junior High School, trying to have the last word. Greta probably isn’t even the one actually writing those tweets. Some snarky adult is doing that, with Greta as their Avatar or Mask.
A real Alpha Male would just ignore the twerp.
