Before preaching to conservatives, go lecture leftists, progressives & liberals if they are guilty of the same thing.
No doubt, your own kind needs to hear your sermon since you agree they commit acts of violence.
Unless of course, you're a hypocrite and endorse left-wing violence.
Just admit it, the left and you love violence and you would not utter a word if the GIF depicted Brandon hitting Trump.
Try again after addressing your hypocrisy and your own party's issues.
