Or, you can just ignore those posts. One should not ask people to only post selectively about their subjective findings only on stuff that you believe have merit. They should feel free to post about anything. Then, we, the readers, can sort through the maze of posts, and only read what catches our interests. No?
Sure that could be someone's approach.
But it's not so simple as that.
After all, you've been in these threads making arguments. You could have just skipped them, but you didn't. Why? Because you see some audiophiles making claims or arguments you disagree with, and you think it's worthwhile to present another viewpoint, presumably.
It's the same for anything we post in audioforums. You could see a post that says, say, that Thiel speakers require TONS of power and will ONLY sound good with super high wattage solid state amps. But if you have reasons to think that claim is false or misleading - e.g. you've heard Thiels sound fantastic with tube amps - then naturally you may want to reply "Hold on, I haven't found that to be the case...here are the reasons why I think Thiel's don't necessarily require the amplification that person claimed."
This is how we hammer ideas around in forums, right? Exchanging different points of view, giving support for our point of view, which can help someone get a bigger picture of an issue, to decide for themselves which avenues to pursue.
