  We show that the model which naturally explains the $\bar u \ne \bar d$
asymmetry in the nucleon and is in quantitative agreement with the Gottfried
sum rule data, also predicts that in the proton $\Delta \bar u > 0 > \Delta
\bar s > \Delta \bar d$ and $\Delta \bar u - \Delta \bar d > \bar d - \bar u >
0$. At the input scale, these results can be derived even analytically. Thus
the violation of the flavor symmetry is more serious in the polarized case than
in the unpolarized case. In contrast, many recent analyses of the polarized
data have made a simplifying assumption that all the three $\Delta \bar q$'s
have the same sign and magnitude. We point out the need to redo these analyses,
allowing for the alternate scenario as described above. We present predictions
of the model for the $W^-$ asymmetry in polarized $pp$ scattering, which can be
tested at RHIC; these are quite different from those available in the
literature.
