Actual Christian here. This decision is not extreme, whatsoever, though I get that it appears extreme to non-believers and feminists. The thing to understand here is that Christians follow the Bible. And conversely, those who do not follow the Bible are not Christian. So let’s take a look at a relevant Bible passage (1 Timothy 2:11-12):
Let the woman learn in silence with all subjection.
But I suffer not a woman to teach, nor to usurp authority over the man, but to be in silence.
Now that’s the word of God. It’s eternal, unchanging, and dictates how He wills us to live.
It’s definitely out-of-step with modern secular culture, and that’s a very good thing from the Christian perspective. We are God’s peculiar people (Titus 2:11-15).
Yes, and some of them are pretty wacky translations. But the underlying word of God is unchanging.
