You are more than entitled to dislike Harry. Having depression doesn't mean you have to like him. He can still be unlikeable. I like Harry but there are times I want to tell him off because of the things he says or does. He isn't always the nicest person.

And besides, everyone is entitled to their opinions, I just think it is annoying when said opinions come from a place of ignorance and misunderstanding. When a person sits there and says they hate how he acted in the fifth book because it was annoying, they sound very uncaring and ignorant of the things he was dealing with, which I think would make anyone who has dealt with depression feel a bit like they can't talk to that person.

Ron's fairly unlikeable often times. He's bratty and selfish and judgmental. Harry has similar traits.

I like OotP, but my opinion is not your opinion and does not have to be. Likewise, I like Harry but you do not have to.
