Ok. Let's be clear. They definitely do make races easier. I mean that's a fact. I've got a source who says it's definitely happenedin the past as he or she was in a meeting when it was discussed years ago.
Sorry Rojo, that doesn't make it a fact, the only thing that's a fact, to you anyway because you saw and heard it, is that someone told you it's "definitely happenedin the past as he or she was in a meeting when it was discussed years ago". Also, you've only got their word that they were in that meeting and heard it, they could be bullshitting to impress, it happens, so that's not a verifiable fact either.
So two non verifiable non facts, that it's definitely happening and your source is being truthful.
