I do think the OP was disingenuous and goady but thankfully most responders have not been.
To those that agree with the OP I agree with others who've suggested educating themselves and perhaps they should start by learning about
White privilege
Othering
Why certain terms are considered racist
Why certain questions are racist
"There have been numerous studies that show that job applicants with a 'typically non-white' sounding name (eg Tyrone, Jamal, Shanice, Mohammed, etc) are far less likely to be called into for interview over a 'white' sounding applicant, even when the CVs are identical (in certain fields, you get double the fun if you're also a woman)."
I've had this, I'm a red headed, very pale skinned Scot but have lived and worked all over the uk/Europe. My first name for my generation was very popular for Caribbean girls, my mum just heard it and liked it she'd wanted an 'unusual' name for me.
As a result I have had reason to believe it's meant I've not reached interview stage, been accused of ticking the 'wrong' box on the equal ops sheet, when I have made it to interview I've wondered sometimes if I've got the interview just so they can claim to be non-racist at least to interview stage...
Dd has also has experienced a little as her dad's of Greek descent and she's inherited his very dark colouring and dark curly hair, she also has almond shaped eyes and has been mistaken for being of Asian or middle Eastern origin, and has been called 'paki' 'terrorist' among other things.
I've friends of various nationalities, ethnicities, Religions etc and seen racism second-hand.
Infuriating that people are still having to deal with this level of sometimes violent prejudice.
So op or anyone that thinks op is right, no it's not acceptable to be racist and claim ignorance, yes you need to think before you speak (and educate yourself so you don't think like that in the first place).
