Nah, you should see what basically every European country did to the 'wrong' sort of Christians during the Wars of Religion.
And the brutal repressions that took place even after the Wars of Religion were over (Louis XIV, for example, sent gangs of dragoons to steal from and rape Huguenots).
A third of Central Europe died in the Wars of Religion, and most countries in Europe almost completely ethnically cleansed themselves of non-coreligionists.
Also, until a wave of liberalism sparked (in this regard, ironically) by the American Revolution, every European country that could get its hands on tropical or subtropical colonies with nonzero arable land was fully committed to massive use of slave labor for cash crops.
