No, it can't be any of the options, because all the options stem from the initial condition:

if everyone from group A (women, the poor, immigrants etc) just happens to violate seemingly coincidental and objective value B

Classism does not fulfill that initial condition, because its values are neither coincidental nor objective.

You could change your statement to be:

In general, if everyone from group A violates personal value B, then:
(a) Value B is intended to specifically marginalise group A
(b) You're not applying your values consistently

I don't agree with your darkness = scary therefore dark people = bad people example. Anyone who actually used that argument to justify racism would really be clutching at straws.
