Ron is a wimp?

Did anyone else had the feeling that Ron doesn´t stand up for 
himself? On OOP, he seems always afraid of an angry Harry; he doesn´t 
react when Fred & George make fun of him for being a prefect, when 
they are testing the Weasleys Wizading Wheezes on first years he 
doesn´t do a thing to stop them, and he can only play Quiddich well 
when the twins drop out of school. What is that all about? Where is 
the Ron that follows the spiders to the Forest, because Hermione is 
petrified, and the Ron that yells to Sirius "If you want to kill 
Harry, you will have to kill us too!", even though he has a broken 
leg?
Any thougths?
