Do you understand that using “do you understand” before each of your opinions makes you a manipulative jerk who resorts to mockery to support his supposedly scientific arguments? Do you understand that that inherently undermines the legitimacy of your arguments? Do you also understand that your use of this crude verbal technique to argue by mere implication is not hidden?
It is a question. Trying to help provide information starts with knowing the information already obtained.
Sorry you don’t like it.
Do you have another wording you would prefer to see?
By the fact, facts are not opinions, regardless of the reader’s ignorance of the subject matter.
Cheers!
Do you understand that is the only way he knows how to talk to people? Do you understand that it drives his wife crazy?
