While I hope Robert Barnes as your legal representative does a good job, it seems he is both a braggard and a sore loser. I was a fan of his, enjoying that he stood up for freedom back in his Ivy School days and recently became part of the defense for Kyle Rittenhouse. But you can only know so much about a person when they are in advertising mode all the time.
As you are probably bombarded with already, a recent event shattered the perspective of him by a great deal of people on his ability. The Alex Jones hosted debate between Nick & Barnes over supporting Israel. If you look at sentiment going into the debate, many people said they were fans of both people. Barnes strategy was to say the phrase Islamo-Fascim repeatedly to the point it became a meme, while Nick took a multi-pronged approach reading Talmud passages and iterated over slights against the US and how even without without support Israel would be fine with its defense stockpile, among other tactics. Coming out of the debate 80% of the people polled across 5 polls declared Nick the winner along with every caller into the post debate show young and old.
Barnes reaction to the loss is what shows his true character. While he was cordial before and during the debate and was posting everywhere he would win, afterwards
Barnes posted a photoshop of him spanking Nick to his twitter. At the time Nick thought they were still acting on good faith replied "Sussy Baka'. Barnes then blocked him and for at least 3 days on twitter, his locals.com, and many of his own and other people's youtube streams were he was seen bragging he won and spending great lengths ranting about how Nick was a Nazi literally, figuratively, alluding to, and making crude remarks to that effect. If he used all the rhetorical devices he was using to smear Nick he might of won. The actual results is that he was causing all those people who liked him to see him as a terrible person because they didn't see anything from Nick to merit such a reaction.
That is more or less the recent story that illustrates what type of character he is.
