Accusing those who support him of "showing enthusiast approval" of his actions is toeing a pretty fine line. He hadn't performed yet, so what would you call it? Goodness gracious. What are you implying here, that the crowd was saying, "Hey, we totally approve of what you tweeted" by cheering? That's garbage, and you know it. You know what they were doing and what the intent was behind it (support for a player on your team). You know what would have been acting like it never happened? Doing nothing. So the crowd did not in fact act like nothing happened. They acknowledged it, and showed support (for the player, not the action), and I would imagine (most) will be moving on.
