Yes, they do.
Prefacing nonsense with "might" does not make it any less nonsense.
There are certain statements where we don't know whether or not they are true. They might be true. They also might not be true.
If I think of an hypothesis that compatible with my understanding but where I don't have certainty that it's true "might" is the appropriate word.
If you think that there no way that it's true than it should be possible for you to prove that it's not true. For me proving that you can't prove that it's not true for claim where I don't know whether they are true is a complicated matter.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
