On the other hand, their bare ankles are showing – Harlots!
Come ye out from among them and be te therefor separated
Try reading the verse in context.
14 Do not be bound together with unbelievers; for what partnership have righteousness and lawlessness, or what fellowship has light with darkness? 15 Or what harmony has Christ with Belial, or what has a believer in common with an unbeliever? 16 Or what agreement has the temple of God with idols? For we are the temple of the living God; just as God said,
The passage is clearly talking about PARTNERING with unbelievers.
I find it interesting you mention this verse, written by Paul, who referred himself as the Apostle to the Gentiles. Can't be an Apostle to unbelievers if one seperates themselves from them. One must go out amongst them.
Jesus' own words in John 17
13 But now I come to You; and these things I speak in the world so that they may have My joy made full in themselves. 14 I have given them Your word; and the world has hated them, because they are not of the world, even as I am not of the world. 15 I do not ask You to take them out of the world, but to keep them from the evil one. 16 They are not of the world, even as I am not of the world. 17 Sanctify them in the truth; Your word is truth. 18 As You sent Me into the world, I also have sent them into the world. 19 For their sakes I sanctify Myself, that they themselves also may be sanctified in truth.
