Partly because he was a nice guy (which you are not), and partly because he was a Christian who "WALKED THE WALK', while most alleged Christians merely 'talk the talk'.
You could be a Buddhist, but the lesson is the same.
You do not deserve to have the name "Reagan" in your nic because you soil it with every post.

I chose a screenname that honors a great conservative icon. If you're a conservative and you believe its important to advance conservatism on the internets premier conservative website, then it only makes sense to take a screenname that is appropriate for that venue. One that represents what conservatism is all about. Think I'll keep my handle. I hope it continues to drive you liberals bonkers.
Maybe you could ask JimRob to change your screenname to "Giuliani Man", or maybe a more generic handle would work better for you. Say, "Liberal Man".
