I'm not saying a secondary is bad as long as you are very careful not to introduce oxygen.Is oxygen such a big problem? I use a secondary fermenter and find that it helps in several ways
However yes oxygen introduced after fermentation has started is bad for your beer. It affects the flavor, clarity and long term stability of the beer all in a negative direction. Ideally you want to minimize oxygen during transfers as much as possible.
