Excellent question.
I have been a Christian most of my life, and I used to ask almost the exact same thing, going right down your list.
Jesus did not hate the Pharisees. He died for them, and several of them (Nicodemus, Joseph of Arimathea, Saul/Paul -- the Apostle, and several others . . . ) became His followers. He told the Pharisees, Saducees and Essennes, the Priests and the Scribes, "Oh, Jerusalem, how I have longed to gather you unto Myself as a hen gathers her chicks, but you would have none of it . . . "
He chastised them but did not condemn them. He railed against them for their hypocritical ways but told them they ought to observe the laws they knew were true and cease being hypocrites.
I don't discipline my neighbor's kids, because they are not mine, and I don't love them quite the same as I love my own daughter, but in disciplining her, I surely wouldn't injure her or abandon her. Jesus was trying to seek and save the lost, just as He is doing today.
And He did not say "go, die and enter hell." No, he said "Repent, for the Kingdom of Heaven is at hand."
How about Zaccheus, the traitorous, thieving tax collector?
("Surely, Salvation has come to this house today.")
How about the woman caught in adultery?
("Neither do I [condemn you]. Go [about your business], and sin no more."
How about the thief on the cross?
("This day you will be with me in Paradise.")
In Romans, it says "God commendeth His love toward us in this, that while we were yet sinners, Christ died for us."
You want an example of people loving their enemies? Hoiw about David, refusing to kill King Saul at any of the multitude of opportunities he had?
What about God sending Jonah to Ninevah?
Why would God give Egypt ten chances to repent and in the process prove that each of their gods was impotent?
Why did God not just slaughter all of Egypt and let Israel have that land too?
How about the Good Samaritan?
Note that Jesus said this in response to a question of what the greatest commandment was.
he said "Love the Lord, your God, with all your heart, all your mind and all your strength, and the second is like unto it . . . Love your neighbor as you love yourself . . . "
A Pharisee from the Sanhedrin demanded to know "Who is my neighbor?"
And Jesus told them the tale of the Good Samaritan, in which a Priest and a minister passed by a hapless robbery victim, left him for dead and went on their way, while a Samaritan (Jews and Samaritans were bitter enemies and would have nothing to do with each other) had compassion on him and went to great effort and expense to help him . . . with no hope of return on his "investment" . . . and Jesus told the Pharisee "Go thou, and do likewise."
This person in your office who is abrasive . . . We all have to deal with such people, and they often hold more power and influence than they ought. I can't address how a non-Christian would handle that. I look at each person as someone created in the image of God, beloved by Him and standing at the precipice of an eternal decision -- Heaven or Hell. I try to treat others in such a manner that they would not reject Heaven by reason of my actions, but I don't know how a non-Christian would handle it. I've been a Christian since I was 3 years old, and I hadn't encountered anything like that by then. Everything I could tell you would involve Faith in Christ and an effort to save the lost.
Does this help answer your question?
As to the Rosary . . .
Mary is not (and never was) divine. She was human, just like you and me, and she is currently dead to this world, just as each of us will one day be, should the Lord tarry. Her only redemption lies in the mercy of Christ, not in some great work, faith or spiritual power of her own.
Mary did not, does not, can not, will not and would not make the promises which have been attributed to her by David, above.
Praying to Mary is of no greater assistance than praying to a stone statue of Molech, except that the demon who owns that statue is a powerful spirit, would be listening and might try to do something for you to enhance your subservience.

I couldn't help but notice that you go by the name "Sugnim," a shortened version of "Meshugnim," meaning crazy, insane, wicked people. It is a term that many devout Jews apply toward Christians out of a lack of understanding of what Christianity really is. We follow the teachings of a Rabbi, One which I would call the Master of all Rabonai, Whose name is Yehoshua, Who was born in Bethlehem, fled to Egypt, returned and dwelt in Nazareth and began a ministry unto all Israel . . .
The biggest difference between a Christian and a mainstream Jew is that Christians believe the Messiah has already come and is coming again.
Catholics, on the other hand, are taught a heretical doctrine that the ROMAN church (small c) replaced Israel, and that Rome is the new Jerusalem, while the Bible specifically states that the New Jerusalem will be exactly where the OLD Jerusalem is, and that it will be the Home of His chosen people, Israel...
The Pink Kitty, the first answerer of this question, has an interesting observation. Yes, that is a tough question, and yes, it requires a lot of thought. Yes, a lot of Christians would go through a few minutes, hours or even days of mental meltdown processing it, but no, our brains were not short-circuiting, thank you.
