I think racism comes from a cognitive bias, that eg, lets you read a text without ever engaging with the broader explanation offered (social mobility, time scale of integration) but instead engange with a side remark about genes.

GP ties negative properties to entire groups without differenciation, this is by definition racist.

To end on a constructive upside, if GP was really concerned about eg womens rights, any kind of stateful intervention should only target that. By being racist and eg trying to associate this issue with brown skins, stateful intervention becomes sweeping. By being more precise, migration politics that targets them all becomes social politics wich only effects some.

Can you see it now?
