Just from the headline, it sounds like a snarky remark he made. Maybe it was in bad taste, but it still doesn't sound like a call for anyone's death. I'll save you the trouble of looking for more examples--there aren't any.
First, this is still not an example of gleefully calling for the violent death of his political enemies. Secondly, he is making an off-the-cuff response to Ms. Rachel's video--it's not an earnest call for anyone's death. His full comment includes his more salient point about what love also entails.
Read your own post again. You said he spent his life gleefully calling for the death of his political enemies. If you think this quote is the same thing as that, you have a problem with reading comprehension--or you're lying.
Simply not true. You don't know what you're talking about. There's a difference between supporting the second amendment and calling for political violence--learn the difference before you spew.
