I am sorry, but I do not understand fully.  I would appreciate it if
some one could explain with more verbosity for me.

I do not understand why data insertion is even, but replication is not.

I do not understand how to solve the problem.  What does "bumping"
tokens entail - Is that going to change my insertion distribution?  I
had no idea you can create different logical keyspaces ... and I am
not sure what that exactly means... or that I even want to do it.  Is
there a clear solution to "fixing" the problem I laid out, and getting
replication data evenly distributed between racks in each DC?

Sorry again for needing more verbosity - I am learning as I go with
this stuff.  I appreciate everyones help.
