Singer Solange Knowles deleted her Twitter account on Tuesday night after an epic rant against white supremacists in the wake of Charlottesville violence.Solange, 31, launched a powerfully worded tirade when she wrote: ‘F** white supremacist. F*** nazis. F*** your stale ass bland ass monuments. F*** asking folks to be graceful.’Solange – the younger sister of Beyonce, 35, – shares son Daniel, aka Julez, with ex-husband Daniel Smith and added: ‘My son’s first day of school has been in the midst of seeing these bulls**t images that still tell him this system was built to be against him. How mofos supposed to have a fresh start with education, seeing this s**t? ‘Thinking about demanding he not be required to take American History because its deep dark rooted ugliness continues to live right now, right before our eyes.’Photo Credit: Getty
