It is now abundantly clear I'm wasting my time, but I have a lot of time and you're trying to bait me into an argument, so what the hell.

The comment you replied to in the first place:

I didn't think this subreddit was as bad as the rest on Reddit

Your comment (your extremely broad, generalizing comment):

Everyone thinks their own community is the exception.

Here is "For Dummies" version of my response:

That's probably true sometimes, but not always true. Here is an anecdotal example of a time when it was specifically not true. The thing I'm referring to not being true is, to reiterate, the thing you said (considering context). In case you forgot what you said already, it was this: "Everyone thinks their own community is the exception."

My comment was not meant to refute what you said (see: The part where I said "That's probably true sometimes"), it was just meant to point out that not everyone thinks their community is the exception. I made the point by telling a story about a community I was part of, while acknowledging there was nothing exceptional about it.

Is this exhaustive explanation enough to help you understand how my comment did in fact address your comment? If you still think it didn't address your comment, please explain what you mean by "address my comment."

In case you still don't get it:

No matter how shitty you think a sub is, it's still going to have users who think it's a good community

No shit, Sherlock. The key here is that you didn't say it's going to have ONLY users who think it's good. Your original comment said "everyone," which is unknowable and demonstrably wrong, as evidenced by my anecdote.

everyone overlooks the flaws of groups they're in

Stop saying the word "everyone."
