Do you find Harry and Ron rude in general?

I was curious about this as I have seen this opinion but I don't think either are in general rude. Of course they have moments of rudeness but when we are introduced to them I think both are quite polite. I think they can be tactless at times but they are polite to most people. Often when they are rude it is when they are dealing with a lot of pressure and stress. For instance Harry in book 5.
