I did indeed give two examples. If you would like links, you can ask.
“If Sarah Palin … does not repudiate her own part, however tangential, in amplifying violence and violent imagery in American politics, she must be dismissed from politics, she must be repudiated by the members of her party,” MSNBC’s liberal commentator Keith Olbermann said....
The Palin criticism started shortly after the shooting, when liberal blogger and Daily Kos founder Markos Moulitsas fired off a series of tweets citing the Palin website that targeted Giffords’ health reform vote. “Mission accomplished, Sarah Palin,” Kos tweeted of the website soon after word of the shooting broke.....
Liberal political consultant and blogger John Aravosis criticized Republican political consultant Patrick Ruffini for praising Sen. John McCain’s statement on the shooting. “Well, McCain’s running mate did put a rifle target on the woman, so not surprising McCain is forced to make nice,” Aravosis wrote...
Other Democrats and liberals expanded their criticism to inflammatory rhetoric of the tea party movement... New York Times columnist Paul Krugman weighed in shortly after the shooting, saying Republicans needed to be held accountable for their tone.....
Etc. so on, and so forth. The shooter turned out to be a complete nutter who thought he was being oppressed by the existence of English Grammar, which did not at all stop the Left from continuing on this line of attack.
Clinton was in deep political trouble in April 1995. Six months earlier, voters had resoundingly rejected Democrats in the 1994 mid-term elections, giving the GOP control of both House and Senate. Polls showed the public viewed Clinton as weak, incompetent and ineffective. House Speaker Newt Gingrich and his GOP forces seized the initiative on virtually every significant issue, while Clinton appeared to be politically dead. The worst moment may have come on April 18, the day before the bombing, when Clinton plaintively told reporters, “The president is still relevant here.”
And then came the explosion at the Murrah Federal Building. In addition to seeing a criminal act and human loss, Clinton and Morris saw opportunity. If the White House could tie Gingrich, congressional Republicans and conservative voices like Rush Limbaugh to the attack, then Clinton might gain the edge in the fight against the GOP.....
Etc. so on and so forth.
The bomber turned out not to be a militia group, but an environmentalist nutter.
There are plenty of comparisons. For example, both are increasingly giving way to justifying violence against the other, but the Left is (currently and recently) worse about this than the Right is.
