> Having your SO question closed as off-topic or already answered isn’t believable to you?

It is believable. But it being a problem I don't see. If it's off-topic, that's sad for you but no reason to feel angry or it being "hostile" or something. It's just off-topic. Same if I started posting lots of local news from my city to HN. It's simply just off-topic and not what the site should contain. If it's already answered, being pointed to that answer by someone spending the time to digging it up is also not rude. Sure, you may feel bad because you feel someone "reprimanded" you or something. But that's on you.

Why do you continue to ask for examples if you're just going to downplay them or explain them away like you did here?

Still haven't been given a single example? And no, closing a question isn't necessarily hostile.

He's demonstrating in real-time to other contributors here why SO is toast hahaha

The feeling you are getting when talking to that arrogant brick wall was the prototypical SO user experience.

No need for name calling. If anything, you're demonstrating what I'm pointing out: emotionally charged responses to perfectly polite behavior.

Emotionally charged? No, just pointing out a statement of fact that conversing with you is like attempting to have a reasonable discussion with a brick wall. That's not emotional, just objective... you are perfectly suited to SO!

You're a Republican voter, aren't you?

Using perfectly polite words does not mean your behavior is perfectly polite.
