The Problem with Genres

I definitely have to agree with Chandler when he says that genres, especially westerns, could be problematic. He states that "genres can therefore be seen as 'fuzzy' categories which cannot
be defined by necessary and sufficient conditions." This statement couldn't be more true, especially when comparing it to Lee K Abbott's story The Purpose of this Creature Man.
The story seems to fall under the category of a western genre when one starts to read the first few lines and there is a 'hold up' which rings true of most westerns, however, there are multiple findings throught the story that would lead the reader to believe that there are many holes in anyone's ideas of a true genre just as Chandler agrees in his Defintion of a Genre.
I have seen many old western movies in my time and never have I known a leader of the outlaw gang of robbers to be a graduate of the "Stillman Academy of chiropractic Medicine in Peoria, Illinos." As Doc robs the safety deposit box from the clerk at the post office, he tells a man, "Son, think of me as an unwelcome but polite relative. In the meantime,stand upright and
square. Posture's lifelong and chronic." That doesn't sound like a typical western robber at all, more like a very well off and educated man.
There are certain lines throughout the story that are remniscent of an old western that keeps it going with the theme such as " Every marshall was trailing us, even the special Indian Deputies from the Nations." However, when I think of any western, I picture the imagery of the outlaws riding away on their galloping horses with a cloud of dust kicked up from the horse's hooves as they race away, not the leader of the gang putting away in his Dodge. Also, I have always thought that the typical western genre male character of a cowboy to be strong and masculine, dirty and spitting out tobacco through the space of his stained teeth, not at all feminine like the character of the Kid, who actually dresses like a woman and recites sonnets.
I guess Chandler is right. No one can actually say that one specific genre has to be a certain way and that is the end all. People are complex characters in nature with many facets and quirks about them so who am I to say that there can't be many genres and sub genres, etc. I have always thought of a western to be a certain way just because of how I have seen it portrayed in the past by society. Maybe that is not so at all.
