Personally I don't think it's a matter or should you, or shouldn't you, the important question is why do you want to? There are plenty of reasons why you can, and maybe a few why you should. So it's hard to say either way without knowing the details.
As far as aerating, you do so in the beginning to help the yeast. If you are transferring to a secondary vessel, the yeast should have completed (or pretty darn close) ferementation. They've already gone through the growth phase, and any oxygen they don't consume will end up in the finished product, so in general, no aerating after fermentation has started.
Did your friend say why he thinks it helps the yeast?
