Always accepting, never admonishing…is that Biblical?

This is an issue that I ponder quite often.  There are many Christians that interpret "love they neighbor" and "Jesus is love", etc to mean we should be all accepting of everything because after all, who are we to judge.  As I have written before I think that is an incorrect interpretation of Scripture.   

Here is some Scripture that seems to speak to this point.

2 Thessalonians 3:6-15(NKJV)

But we command you, brethren, in the name of our Lord Jesus Christ, that you withdraw from every brother who walks disorderly and not according to the tradition which he received from us. 

For you yourselves know how you ought to follow us, for we were not disorderly among you; 

nor did we eat anyone’s bread free of charge, but worked with labor and toil night and day, that we might not be a burden to any of you, 

not because we do not have authority, but to make ourselves an example of how you should follow us.

For even when we were with you, we commanded you this: If anyone will not work, neither shall he eat. 

For we hear that there are some who walk among you in a disorderly manner, not working at all, but are busybodies. 

Now those who are such we command and exhort through our Lord Jesus Christ that they work in quietness and eat their own bread.

But as for you, brethren, do not grow weary in doing good. 

And if anyone does not obey our word in this epistle, note that person and do not keep company with him, that he may be ashamed. 

Yet do not count him as an enemy, but admonish him as a brother.

Hmm.
