I am going to take a few minutes and try to explain something to you, on a serious not. You continue to say things like this post where Trump is being called a cult leader and people like you are considered cult members. In addition, you say that personal experiences do not count as you cannot judge a group by what one person does.
Having said that, let me begin.
The study of human behavior is called psychology. Psychology is a scientific discipline that focuses on understanding human behavior and mental processes. It encompasses a wide range of topics, including cognition, perception, emotion, motivation, personality, social behavior, and mental health.
Humans have established patterns of behavior that have gone on for centuries (since humans began) and there are patterns of behavior that signal what what the person is likely to be, how they think and act, and what guidelines they follow. There are different types of behavior and that doesn't mean that because they are different that they are bad/negative. Nonetheless, some behavior patterns do signal problems that are negative.
There are many articles written by experts on human behavior (psychologists) that state that Trump is acting like a cult leader and that those following/supporting him are cult members.
Their evaluation is likely to be correct and definitely more likely t be right than your evaluation, given that you are not an expert on the topic.
Here is an book that you may want to buy and read as it gives the information in detail:
The Dangerous Case of Donald Trump: 27 Psychiatrists and Mental Health Experts Assess a President Hardcover
and here are some articles you may want to read as well:

None of this is bias or opinion. It is the evaluation of experts in the Psychology field.
