Brony, they are Jews.
Being Jewish does not give someone immunity from middos problems. We are luckier and more obliged to be better because we have the Torah.
In fact, I have heard it said by a phenomenally great rabbi that yidden are the fiercest nation on earth, but it is to be tempered by Torah.
You would think if someone looked and acted the part that it would be enough. Well, they (all of us) have to dig deeper at times.
