I don't object to these comments being downvoted: 1 2 3 4. The first one is unfoundedly dismissive about evidence opposing one's own argument, the second presents evidence against one's own argument (even in failed demolitions, buildings don't actually fall over) and tries to present it as evidence for the argument, and the third claims to provide links to original sources without actually doing so. The fourth is making a bold claim that contradicts scientific research, without really backing up that claim in any way.

I do object to these being downvoted (this list includes some that don't have a negative karma now, but did before): 1 2 3. The first asks an honest question, the second seems to provide a reasonable answer to the question presented, and the third makes a perfectly valid query.

I'm ambivalent on these being downvoted: 1 2. The first one is made in a tone that is possibly a bit too confident and it does feel like it's grasping at straws a bit, but then the first two sentences do make a very valid point. The second is implicitly throwing its support behind the conspiracy theory interpretation without backing it up any more, but then it is drawing attention to the fact that the parent was needlessly downvoted. It's also good to express that some particular question might be important, but at the same time it would again be nice if a better explanation would have been given regarding why it's important.
