John the Baptist said the following:
Matthew 3:7-12
7 But when he saw many of the Pharisees and Sadducees coming to his baptism, he said to them, "Brood of vipers! Who warned you to flee from the wrath to come? 8 Therefore bear fruits worthy of repentance,
9 and do not think to say to yourselves, 'We have Abraham as our father.' For I say to you that God is able to raise up children to Abraham from these stones.
10 And even now the ax is laid to the root of the trees. Therefore every tree which does not bear good fruit is cut down and thrown into the fire.
11 I indeed baptize you with water unto repentance, but He who is coming after me is mightier than I, whose sandals I am not worthy to carry. He will baptize you with the Holy Spirit and fire.
12 His winnowing fan is in His hand, and He will thoroughly clean out His threshing floor, and gather His wheat into the barn; but He will burn up the chaff with unquenchable fire."
And Jesus Himself said the following:
Matthew 12:25-37
25 But Jesus knew their thoughts, and said to them: "Every kingdom divided against itself is brought to desolation, and every city or house divided against itself will not stand.
26 If Satan casts out Satan, he is divided against himself. How then will his kingdom stand?
27 And if I cast out demons by Beelzebub, by whom do your sons cast them out? Therefore they shall be your judges.
28 But if I cast out demons by the Spirit of God, surely the kingdom of God has come upon you.
29 Or how can one enter a strong man's house and plunder his goods, unless he first binds the strong man? And then he will plunder his house.
30 He who is not with Me is against Me, and he who does not gather with Me scatters abroad.
31 "Therefore I say to you, every sin and blasphemy will be forgiven men, but the blasphemy against the Spirit will not be forgiven men.
32 Anyone who speaks a word against the Son of Man, it will be forgiven him; but whoever speaks against the Holy Spirit, it will not be forgiven him, either in this age or in the age to come.
33 "Either make the tree good and its fruit good, or else make the tree bad and its fruit bad; for a tree is known by its fruit.
34 Brood of vipers! How can you, being evil, speak good things? For out of the abundance of the heart the mouth speaks. 35 A good man out of the good treasure of his heart
F57 brings forth good things, and an evil man out of the evil treasure brings forth evil things.
36 But I say to you that for every idle word men may speak, they will give account of it in the day of judgment.
37 For by your words you will be justified, and by your words you will be condemned."
I think I would do what He did (and don't forget the cleansing of the temple)
