If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
You're refusing to address someone's stated argument, and in fact, are saying something that is nonresponsive if he means what he is actually saying.
Yes, sometimes you have to do that. But making it your default behavior when addressing all people in the real world who don't agree with you is a bad idea.
Who said anything about making it your default behavior? There's a difference between "many" and "most", and an even bigger difference between "many" and "all".
