Before he even ran for office? Was it when he went down the escalator? When he was nominated? When he won the election? In the last year? And if you like, tell me source of information you used that made you begin hating him. (optional).
(Luckyone smacking his hands with joy to answer this question)
I had very little knowledge of the man before he started running for office but when the media started covering him in 2016 I began to get a picture of what kind of a person he was when younger, The first item that came to view was that he was sued by the Justice department of racial discrimination in 1973. A lawsuit that he later settled, meaning he acknowledged guilt through his pockets but not acknowledged guilt with words and deeds. I have never discriminated against anyone and is one of my basic rules of conduct, so that started to give me a bad taste about the kind of a man he is/was.
I then started to listen to him and what he was saying against Muslims and about Mexicans. Since I was born and raised in Mexico and lived there for the first 18 years of my life and know Mexicans well and generally have a good opinion of them being friendly, honest, and good people and he talked about them in such a bad way, I started to dislike the man. That was followed up with the 25 sexual misconduct allegations against him, the proven fact that he cheated on his wives (something I do not believe in) and the debasing attacks on Hillary (a woman), I started to realize the man was the kind of a person that I do not approve of. Exactly the opposite of what my parents taught me to be and who I strive to be.
All of this was followed by him separating children from their mothers and then even worse, not keeping track of where they were being kept or sent so that they could reunite in the future generated my first feelings of hate against the man. To me, that was the act of a heartless person and 100% against what I believe in........which is, family is the most important thing in life. In addition, his abasement of everyone that disagreed with him and even more so of patriots like John McCain, who I was not in favor of becoming president but who was someone I respected highly because of what he gave for his country and what he stood for. The abasement of the gold star family at the republican convention and the way he talked about women in general, made me come to hate him as being everything I despise in a person. Not just one thing, but everything.
From there on in, my hate grew with his incompetence in handling issues of the country, his belief that he is above the law, the 3500 lawsuits from people he worked with or were partners and his ability to defraud them after they did their jobs, his inability to keep good people on (such as Mattis and McMaster) and his desire to have yes people around him. Him doing things by his gut without taking the time to read, to study, to seek opinions from others and my hate became cemented as I realized that at age 74, this man had no desire to learn and to be the best he can be but simply do what he wants no matter who gets hurt.
I came to realize he does not represent "any" of the things I believe in. In fact, the total opposite. As I have stated often, no one is perfect but if at least one of the following things (morals, ethics, principles, or humanity) are found in the person, I do not hate that person. I may disagree with the person and likely won't "like" the person but then again that is the normal way life is. Nonetheless, to have none of the virtues at all, that becomes a person to hate and to fight against, The same way as if you found a mate that had many or all of those qualities, become someone to love. Just as I love my wife to the nth degree, I hate Trump to the nth degree.
