So if people don't agree with you that also means they hate you?
More importantly, it reassures them of the righteousness of their faith and beliefs because Jesus predicted they'd be reviled and persecuted for them. What they seem to overlook is that Christ emphasized meekness, mercy, and love above all else. They're just intolerant, self-righteous dicks.
The Real Jesus, the Jesus of the Gospels, shows no signs of standing with the economic elites of His time. The Sermon on the Mount, the core of Jesus' Teaching, is no appeal to supply-side economics. Jesus tells people to give to the poor -- not to the rich. That sounds more like a modern Jewish view of the world than like what I see in fundamentalist Protestantism. He saw the rich and powerful of His time corrupt, callow, and exploitative.
If you want to know the Real Jesus, then read and re-read the Sermon on the Mount until you can quote it as easily as you can quote your favorite movie lines... to the level of "Play it, Sam. Play it again". Or "Toto, I don't think we're in Kansas anymore". Sort of.
Jesus was not hostile to rich men in the Bible. He did test the Rich Young Ruler, but Jesus loved him very much. Zaccheus was a tax collector; Jesus drew Zaccheus to Him, and before the night was over, Zaccheus (who was very wealthy from being a tax collector) promised to restore fourfold the amounts he had overcharged folks. Jesus had no problems paying taxes to Rome; he told the Israelites to "render unto Caesar what is Caesar's" and to, essentially stop whining about it.
Jesus did not oppose any man; he came to seek and save The Lost, but he was most firmly opposed by the Religious Elites. It was the Religious Elites, not the rich, that he reserved his harshest pronouncements for. It was the Religious Elites against whom he poured out His Righetous Wrath, overturning the tables of moneychangers in the Temple. He's that way today. There are many on the left, as well as on the right, that seek to prove Jesus agrees with them. "They honor Me with their lips," said the Master, "but their hearts are far from me." This, sadly, is true about lots of folks that lean on Jesus when He agrees with them, but won't bend in other areas so they conform to Him.
