Oh the racial bias is much easier to find, just start typing for "are white people". The suggestion list is perfectly happy with "are white p" and "are white pe", but literally vanishes as you type "peo". It does not do the same thing as you type "are black peo" (...ple more athletic, "what is a blue black person", "is wearing black bad", "how does wearing black affect you"). It's like they don't think white people are people, or don't want you talking about them as a group.
If it were objective, you'd think it would try and suggest something for all queries just to be maximally useful. But it doesn't. I mean surely people have asked questions that start with "are white people" why not show the most common one, or the most controversial, or the "highest quality" whatever that is. But no, absolutely nothing.
Someone clearly has their thumb on the scale.

Nah, this one is super obvious in the lack of an Easter doodle, but every other religion gets a shoutout on their important days. Just like the lack of one for International Men's day. Google's bias is as predictable as every other (D-CA).
