If Bono claims to be more focused on his tango than controversy, the team around him is certainly paying attention.
In an interview with ABC News, Bono adviser Howard Bragman singled out OneMillionMoms.com as what many, he said, consider to be a "hate group," and said there was "no way" his client would back down.
"What I tell people to do, my clients, is ignore it. It's people writing on a bathroom wall," Bragman said of the online comments. "A lot of people put their hate opinions on email, and the vast majority of it is anonymous."
Bono's mother, Cher, came to her son's defense on Twitter, posting "lovelies! Chaz is Being Viciously Attacked on Blogs & Message boards about being on DWTS! This is Still America right ? It took guts 2 do it."
She urged her 340,000 followers to pledge their support for Bono on other social media sites.
"I support him no matter what he chooses 2do," Cher tweeted. "It took courage to do DWTS!"
"There's nothing to get a mom on board than talking badly about their kid," Bono said today. "I really appreciate it. She's just been amazing."
Whether Cher's support for her son will go so far as to include an appearance on the show this season remains to be seen – "We'll see" is all Bono would say when asked on "GMA" – but the woman he will dance with on the show, professional dancer Lacey Schwimmer, is standing just as firmly behind him.
"I was absolutely thrilled. I've always been a huge supporter of the LGBT community and I couldn't be more excited to have Chaz. Not only is he Sonny & Cher's child but he's also a generally cool person," Schwimmer told The Insider last week.
Bono's competitors and the show's producers are coming to his defense too.
HLN legal analyst and talk show host Nancy Grace told ABC News, "Unless Chaz commits a felony, I don't have a problem … I just don't think it's our business to be judging other people for their personal decisions."
The man responsible for including Bono in the controversial celebrity lineup, "Dancing With the Stars" executive producer Conrad Green, hopes the voting public will put their personal opinions aside and let Bono's dance moves do the talking.
"We think Chaz is a great guy with a really interesting story," Green told ABC News. "One of the great strengths of our show is your ability to have preconceived ideas about people, but when you actually see them in the show, you might well end up with a different opinion of them."
Focused on Dancing
Staying true to his word and putting controversy aside, dancing is just what Bono and Schwimmer have been focusing on around the clock to prepare for the show's two-hour season premiere, less than two weeks away on Sept. 19.
"I've been pretty good at getting the steps down so I think it's just stamina, getting that up, going into it," he said of the duo's preparations. "We're working on our first dance right now. It's very challenging, but I'm actually enjoying it."
The show's strict practice regimen is notorious for simultaneously providing a weight loss miracle for the celebs who compete – last year's finalist Kirstie Alley dropped four dress sizes - and Bono is proving no exception.
"I think I'm down like eight pounds now," he said.
Calling it "really hard" to pick a front-runner for Season 13, Bono told "GMA" he and Schwimmer have yet to determine who their biggest competitors will be.
"I'm really not going to know until that first night, just like everyone else," he said.
No matter how long he lasts on the show, Bono said he hopes his participation will be a teaching lesson, not a rallying cry or controversy, for parents and kids.
"For all the teens and kids out there with gender dysphoria, I think it's going to have a really positive impact," he said. "I know that when I was growing up if I had seen a show like this, with somebody like me, it would have made all the difference in my life."
