Molina ejected as Cards lose

Cardinals 37-18 vs Giants  29-27

Let’s start bottom 3rd 2-0 Giants . Cardinals batting, Yadier Molina hits a groundball great play by Brandon Crawford dives and throws and gets Molina out, Molina throwing his helmet onto the ground he is ejected. What I want you to tell me is: Is it fair to eject someone for throwing their helmet? Top 7th 2-2 Giants batting  Brandon Belt knocks a 2RBI double into the outfield and the Giants go on to win 4-2, but was it fair that Molina was ejected?
