Racism is inferring personality (and other) traits based upon genetics, not "where someone was born."
I would argue that your genetics, unlike your star sign, is fairly meaningful.
This gets into the social construct of what makes a race and what qualifies as racism. For example, often discrimination based on ethnicity and not race still gets classified under racism even though it wasn't based on race. For a purely pedantic sense, it is ethnicism or some such word that doesn't seem to exist, not racism. Yet we generally recognize it as 'close enough' and group it together. Birth place discrimination can often be thrown in for the same reason, especially if there are racist beliefs concerning birth place that factor into the logic (assuming that anyone born in Asia must be Asian).
Close enough to count if this were horseshoes.
Oh I like that one. Inferring personality traits based on where someone was born - "Racism". Inferring personality traits based on when someone was born - "Astrology".
"but she couldn't see the issue."
What a surprise...
