I see no reason at all to "admit" it. I think he's perfectly capable of being a legitimate Trump supporter, albeit one of questionable judgement and emotional stability.
Why are you so worried about what people who hate your guts are going to say about you regardless of the circumstances? They're talking out of their asses. You know it. I know it. And THEY know it.
If violence actually bothered them, they'd be hard on their own. The left makes these absurd accusations because, like African-Americans, they've learned many on our side will make asses of themselves trying to disprove a negative.
No, antifa does things like sending bombs to people. But doing things like that is entirely separate from being a Trump supporter.
You’re falling right in line with Maxine Waters. She also wants to pin this on Trump.
“I think the president of the United States should take responsibility for the kind of violence that we’re seeing for the first time in different ways,” Waters said. “I think the president of the United States has been dog whistling to his constituency … and I think that they’re acting out, but they believe the president wants them to do and the way that he wants them to act.”
