[Mod note: for balance, tests for anti-semitism and anti-muslim bias added in comments]

The problem with this 'test' is that it positions all Christians as a monolithic group. And as a result, it's produces questions lik this: Christians are narrow-minded and intolerant of other viewpoints.

Many of my friends who are devote Christians fully support LGBTQ rights. But there are many Christians who are narrow-minded and intolerant.

So, I ended up neither agreeing nor disagreeing with most of the questions yet still came up with "anti-Christian bias."

Took those and moderate islamophobia and miniscule antisemitism

Well, then you know what you need to work on.
