Kick them. If being rude and offensive then have the league manager have a 3 strikes Policy but it needs to be enforced
You can kick them, but they can rejoin at this moment just five mins before the race and still particapte.
At the same moment managers who just have an outburst, when they are pretty friendly normal will have to start over then with a shit car. A one race ban, who doesn't hit the car too much, would be the best.
