There is one difference.

I read what Reiner said about Limbaugh.

I actually had some respect for Rush. Even though he ushered in an era of hate radio, he at least had talent and an entertaining schtick. I could disagree with him profoundly and find him entertaining.

That say, it was classless of Reiner.

Reiner was never the President of the United States.

Maybe he could be a jagoff at times too, but he never had the power to make decisions that affect my life.

That to me is the difference. He speaks on behalf of more than Donald Trump, but on behalf of the nation. The sick narcissist can't differentiate the difference.
