Just search for "kill clarence thomas" on Twitter. There's tons of stuff there. A conservative source reported on it, but unfortunately did not bother to archive the tweets.
Interestingly, there was far less for "kill Sam Alito" and "kill samuel Alito" - even though he was the guy who wrote the actual opinion. They really, really hate Clarence Thomas.
Hopefully a distant relative, because he's on the short end of the gene pool and it's filled with piss.
