Why did some whites believe that the african american protesters in montgomery were behaving arrogantly

At that point in history, protests and activism were a lot less common than they are nowadays. Moreover, Black people had never organized themselves and protested in such an open and clear way. The fact that they were demanding change from the government made them seem arrogant to some people. This was particularly true for people who believed that change should only come from slow reflection and through democratic and pacific means.
