It depends on what you mean by "poacher."
There's the relatively harmless type who simply hunt bountiful species (such as deer) out of season, on government property, or without a license -- but still do so in a sporting way. I believe there's something to be said for at least considering the ecological justification for some hunting laws before you go breaking them, but obviously other laws, such as the required hunting license, serve only to generate profit and can thus be stealthily ignored.
I'm assuming that you think of yourself as being in the first category, based on the romantic Robin Hood allusion!
The other type of poacher is, to borrow your phrase, "beneath my contempt": firing from roadways, using spotlights, targeting exotic endangered species, taking trophies, and generally showing no respect for the tradition of the hunt. I believe that this second group is what most people will most closely identify with the word "poacher," in this day and age, so . . . keep on doing what you're doing if it's sustainable and fair play, but be careful about describing yourself as a poacher.
Also, try bow hunting if that isn't already your chosen method. Gratifying, silent, and a little more natural.
