Yeah, but that black *** only did this because of Trump and Pence; so it's their fault - Liberalism 101.
That's the assigned talking point isn't it. Anything liberals do to conservatives no matter how intolerant, hateful, unfair, dishonest, harmful, disrespectful, cruel, destructive, and/or deadly is President Trump's fault, or Republicans fault, or conservatives in general fault because they 'inspire or provoke such behavior'.
And the intolerant, hateful, unfair, dishonest, harmful, disrespectful, cruel, destructive and sometimes deadly progressives/liberals/statists/leftists etc. are pure as the driven snow and/or forgivable because after all, they hold the righteous ground, are morally superior, are nicer people, and they have the right motives. Just ask them.
And of course THEIR rhetoric, actions, etc. don't inspire bad behavior from anybody because THEY are righteous and nobody else is.
I don't know how we counter that because they have most of the media, most of education, a lot of scientific groups, a lot of big business and therefore a lot of money on their side, but if we are going to save America, we sure need to figure it out.
