I was struck this reading by the fact that the introduction of Mr. Hurst is not necessarily disparaging. Mr. Hurst, merely looked the gentleman, could be a description from the viewpoint of the assembly. If the women of Meryton were husband-hunting for themselves and their daughters, a married man would be of little interest to them. He, like the Bingley sisters, is quickly passed over, while the descriptions of the single men are detailed. Who at the ball really cared if Mr. Hurst were a true gentleman or not? We don't necessarily need to assume that he's not at this point.
