The same thing probably applies to ageism. Sure, you can tap dance around putting a lot of specific dates on your resume. But generally it's pretty obvious within a decade or so. And, if you really go whole hog and don't even put any durations, you probably don't want to look like you're maybe just out of school if you've just had a couple long duration jobs--and the company's application form will probably make you fill in dates anyway.

Racism can be very subtle and insidious, though.

You don't always need to talk them out of beliefs like "we are going to take your country away from you," it's more about dispelling unexamined gut beliefs like "the best candidate will probably visually resemble the people who have been good in that role before." The latter is less difficult to overcome if you can get yourself into the face-to-face stage.
