This is 100% correct.

I also think it's important to distinguish politeness from respect. A random stranger that you meet on the street, deserves your politeness until they give you a reason to not be polite. However respect is a much more complex thing, involving appreciation for ideas and their quality of character, which is simply not something that you should give out until somebody has earned it. It doesn't take long to earn respect, you can earn mine within a day, but you can also lose my respect within the same amount of time.
