Ah yes. Observe the following video. Notice the blonde in particular. I'm sure she would say the same, whatcha think?

You are getting this the wrong way.This issue does not apply to non believers,they do not believe and they operate in a different kingdom.Sinners sin so if you take yourself from them how will you preach to them?Even the bible in the scripture I gave says the same,if we were to be asked not to keep company with fornicators in the world then we would need to be out of the world.The world fornicates every day but Christians it's different.The women in your video are wrong and those actions are mean.They have no love whatsoever and it will be difficult to get that woman saved.Even in church,it's not like people fornicate and they are chased away immediately.If people repent (change of heart and actions,meaning they stop fornicating) then they have no issues.It's different when you continue fornicating and you have been warned already,in that case they chuck you out.
1Co 5:1 It is reported commonly that there is fornication among you, and such fornication as is not so much as named among the Gentiles, that one should have his father's wife.
1Co 5:2 And ye are puffed up, and have not rather mourned, that he that hath done this deed might be taken away from among you.
Note even in this case,Paul is surprised that the church has not mourned this person would be removed from them.This is what was expected.Churches will chuck you out if you want to live in sin.It is better that you are brought before the church and your case is talked about than that the church prays for you to be taken out.Believe me you will suffer in a big way.
1Co 5:3 For I verily, as absent in body, but present in spirit, have judged already, as though I were present, concerning him that hath so done this deed,
1Co 5:4 In the name of our Lord Jesus Christ, when ye are gathered together, and my spirit, with the power of our Lord Jesus Christ,
1Co 5:5 To deliver such an one unto Satan for the destruction of the flesh, that the spirit may be saved in the day of the Lord Jesus.
1Co 5:6 Your glorying is not good. Know ye not that a little leaven leaveneth the whole lump?
1Co 5:7 Purge out therefore the old leaven, that ye may be a new lump, as ye are unleavened. For even Christ our passover is sacrificed for us:
This was Paul's directive and this fornicator was delivered to Satan.He suffered a lot in his life then later you will find that Paul was asking the church to have mercy on the guy.Of course the guy repented later and was restored.
You can go and fornicate in certain churches where that kind of behaviour is tolerated.You do that in other churches and live to regret.
