Would Jesus "shun" someone?

I have a question about a scripture, it's Matthew 18:15-17

15 “If your brother or sister sins, go and point out their fault, just between the two of you. If they listen to you, you have won them over. 16 But if they will not listen, take one or two others along, so that ‘every matter may be established by the testimony of two or three witnesses. 17 If they still refuse to listen, tell it to the church; and if they refuse to listen even to the church, treat them as you would a pagan or a tax collector.

Jesus speaks here about relationships where one person does something clearly wrong.

There is a process explained where the issue gets worked out, but if it doesn't, it says you are too treat that person like a pagan or tax collector.

Most times I have heard that scripture talked about, it was strongly implied that we are to totally cut ourselves off from that particular person. In other words to "shun" them.

I was reading this Sunday morning and something occurred to me. Jesus would never advocate for us to hate anyone or to ignore anyone using the "silent treatment". 

So what did he mean?

I was thinking about this and then I realized that Jesus was KNOWN for hanging out with "pagans and tax collectors"!

Luke 15:1
Now all the tax collectors and the sinners were coming near Him to listen to Him.
Matthew 9:10
Then it happened that as Jesus was reclining at the table in the house, behold, many tax collectors and sinners came and were dining with Jesus and His disciples.

Interesting eh? Then I saw THIS ONE:

Matthew 9:11  When the Pharisees saw this, they said to His disciples, "Why is your Teacher eating with the tax collectors and sinners?"

Seems to me that Jesus was not "shunning" them. It WAS a different kind of relationship, but it was not one of exclusion. It was not "I'm holy and you're dirty rotten sinners."

It has made me re-think how the church is taught about relationships where someone does something wrong.

I know some of you reading this will immediately start thinking about the situation in Corinth. (1Cor Chapter 5) 

 I thought of that to. 

 
How does this relate to that situation and what are YOUR thoughts on this?
