Anaerobic weed soup bad for soil?

Dr Elaine Ingham on Diego's Permaculture voices said that anaerobic is bad for the good bacteria. Yet my yields increase with using yucky comfrey weed soup. Should I stop using it and switch to compost tea?

Why would you stop doing something that is yielding good results? It is true, in general, that beneficial bacteria prefer aerobic environments and anaerobic environments favor pathogens. Your comfrey soup may be anaerobic but your soil almost certainly is not. The very act of putting the comfrey soup on the soil aerates the soup to some degree, and then as it works its way into an uncompacted soil it is getting more exposure to air.

Getting good results argues that what you are doing is working.
