Ah, Tommy Robinson. Took a quick Google to work out what you were on about.
This story like, so many, is a passing thing, so it's only going to be briefly relevant. The question is whether you genuinely support the right wing politics he espouses, what with having founded the England Defense League, and whatnot. If you do, then you are well within your rights to express your allegience through your music, as many bands have before.
If you don't agree with his viewpoint, but are hoping that using a controversial topic for the theme of a band will 'get you there', rather than look like a savvy business move it smacks more of desperation and clutching at straws, not to mention a pretty cynical sellout. Moreover, rather than net you the kind of success the Pistols achieved (and I'd suggest they were presenting something more nihilistic and anarchistic than right-wing anyway) it would likely guarantee you the kind of marginalisation that many other NS, racist, and bigotted bands have been served.
While every viewpoint is valid, you already know you are flirting with a very unpopular one. There may be avid support in some circles, but the majority of folks will find it tasteless, and very likely not give it the time of day, just like all the other right-wing bands out there. IMO, of course.
