I'd rather our players show emotion and stand up for themselves than be all gentlemanly. Being nice gets you nowhere in the grand scheme of things.
In recent weeks I've seen Kante have a free reign to persistent foul for 90 mins, which includes wiping Dave out at the knee, and not being booked. Then in the same game, watched Delph get a yellow card for his second challenge. I've seen us be denied the most clearest of stonewall penalties you will ever see against Liverpool and then give away a soft penalty. Then when our captain talks to the ref he gets booked.
If referees applied the laws of the game consistently and fairly and stopped trying to engineer the result, then there would be no need to wave imaginary cards.
