I did read your post. I am clearly not the one being dismissive here. You commented with the express purpose of dismissing Rand and all the good points people have made about him, over one tiny, purely emotion-based negative you see in him.
You are nitpicking at details and getting all upset over something that doesn't affect the real world. The endorsement is what you're upset over, and you're specifically pointing out reasons why it made you upset. But all of it is emotion-based, none of it has anything to do with his record.
