If Brits are known for their good manners, why are British subreddits so full of rudeness?

Often one of the things that comes up a lot on British subs is that we have good manners and are very polite. I have seen very little evidence of this on replies to posts.

Are Brits actually as polite and well mannered as we think we are? If so, why are so many so incredibly rude and unhelpful on Reddit?
