Sure sounds like an argument for one who likes to drink!
That's a pretty big assumption on cathoicism's part. So again...some context of this verse will bring things into their proper Biblical perspective.
Luke 7:31-35
To what then shall I compare the men of this generation, and what are they like? 32They are like children who sit in the market place and call to one another, and they say, We played the flute for you, and you did not dance; we sang a dirge, and you did not weep. 33For John the Baptist has come eating no bread and drinking no wine, and you say, He has a demon! 34The Son of Man has come eating and drinking, and you say, Behold, a gluttonous man and a drunkard, a friend of tax collectors and sinners! 35Yet wisdom is vindicated by all her children.
The Pharisees and the lawyers were attempting to discredit the Son of Man with these charges. They had rejected John the Baptist and now they were rejecting Christ.
Notice Jesus says, "you say" referring to the Pharisees and lawyers leveling these charges.
They first attacked John accusing him of having a demon. (very alinsky like these Pharisees)
Did John have a demon?
Not based on the Bible. Jesus just said he was greater than anyone born of woman. (btw...that would include Mary) So their first charge is false.
Next charge from the Pharisees and lawyers..."you say", "Behold a gluttonous man and a drunkard."
Did Jesus eat? Yes. Was He a glutton? No. For that would have been a sin and we know Jesus did not sin.
Did Jesus drink wine? Yes. At communion He drank wine. It was the symbol of His blood.
To excess?
No, for being drunk would have been a sin and we know Jesus did not sin.
Two of the worst groups in society from the Pharisees perspective were the tax collectors (often appointed by Rome and who used their office to benefit themselves) and sinners in general.
Again, the Pharisees are attempting to discredit His character. It's not the only time they did it.
These are the same ones who accused Him also of casting out demons by the power of Beelzebub.
I'll ask you....did Jesus cast out demons by the power of Beelzebub?
