People with allergies already have to worry about hidden stuff like peanut oil. I'd imagine they'd just avoid this specific restaurant entirely.

Then they don't go there.

Reasonable accommodations are just that. Reasonable. The schtick of this place is that there's a high degree of uncertainty involved.

people with allergies probably shouldn't go there.

You think only White people have food allergies?

That's... well, it's racist, but it's so utterly bizarre I can't even get angry.

This study found that in the US, food allergies are actually more prevalent among African-American and Hispanic children than among (non-Hispanic) white children:

What would make you believe that?

And do you still believe it after the other user linked an article about allergies in other races?

While that's a ridiculous belief, it isn't a racist belief.

It’s racism in the most direct sense. Suggesting one race in the case white people are inherently worse than all other races.

It’s not discriminatory, but racism is a belief not always an action. https://en.m.wikipedia.org/wiki/Racism

In fact - it isn't racism, according to the link you have provided.

"Racism is the belief in the superiority of one race over another."

Superiority is a key word here. The link actually ends up on the page for supremacism:

"Supremacism is an ideology which holds that a certain class of people is superior to others, and that they should dominate, control, and subjugate others, or are entitled to do so."
