It may have been a mistake to immediately follow up your assertion that Black Americans are racists with a cop-thief analogy.
Perhaps.
On the other hand, your appraisal is only salient if viewed through a cynically racist filter... whereby you could be assumed the racist for interpreting it thus. It is therefore probably best to assume that the individual(s) is/are not racially motivated until they prove otherwise.
I'll gladly extend you that courtesy.
