I think that the main concern is the attempt to replace discussion of one oppression with discussion of another, rather than attempts to think of several types of oppression *all at once* which I think is useful and really important.
As thelana says, shared experiences of oppression can be a useful bridge between people - as long as that experience isn't being used to invalidate someone else's experience, which does often happen and is profoundly upsetting and disconcerting.
I would add that some forms of oppression other than race are also visual, and that there are constant attempts to force or require people with "invisible" oppressions to perform them in visually legible ways so that they can be policed and controlled - so I wouldn't completely discount the visual in other cases.
However, every form and experience of oppression is also unique and irreducible.
