Why are you still talking about Hillary?
If Trump murdered a prostitute, you'd step up and claim that somebody else murdered a prostitute too. It doesn't matter. Hillary's sins might be numerous, but Trump's sins are his own, and everytime you say: "… but Hillary" it makes you seem unintelligent. That's not a read, that's not a personal attack, it's a perception, an observation. If person X does something, you do not retort by saying "but person Y did it too."
