I find it strange that when people defend so called “race science” today a common argument seems to be along the lines of “this is correct because some people have negative emotional response to something”. While having a negative emotional response to something certainly isn't an counter argument in itself and isn't a pro argument either! A viewpoint isn't correct merely because it pisses some people off.
Either way, as far as I know, biologist haven't really considered human races to be biologically meaningful category for quite some time now opting clines[1] which are not discrete, but gradual genetic variations over geographic areas, nor does it follow the traditionally defined racial lines. This is why I'm quite suspicious of people pushing so called “race science” as AFAIK it simply doesn't seem to have evidence behind it, rather, it seems to have specific political viewpoints behind it generally.
