In order to avoid oxidation, I don't oxidate my fermented wort. You almost have to TRY to oxidate your beer in order to actually adversely oxidate your beer. A slow stir won't do it, and light twirl won't do it. When I was a newbie, I even straight DUMPED my primary into my bottling bucket THROUGH a strainer at about 4 feet....I saw some obvious and plentiful oxidation (i.e., bubbles/foam), but lo and behold, no off tastes in the final product once it was done.
Seriously, as long as you don't attach a wisk to a power drill and go to town on your fermented wort or drop in a box of Alka Seltzer at the same time as an industrial strength vibrator or something, you ARE NOT going to noticibly oxidize your beer with just minimal caution and some common sense.
Don't worry about a thing....every little thing is going to be alright!
Be more like Bob Marley and the Red Stripe guy and less like Sheldon Cooper and Monk....the enjoyment of your hobby depends on it!
