Charlize Theron’s decision to let her 4-year-old adopted son, Jackson to wear a Walt Disney Elsa costume has cause some opinionated twitter users to harshly criticise the Hollywood actress on her choice. Some of them were so outraged that they dubbed her unfit to be a mother. Some Twitter users were unhappy seeing a little boy dressed in what some consider little girl attire, and expressed their discomfort and concern with aggressive tweets shaming the award-winning actress.What brought on such furore? This week, a photo surfaced of the actress and her son Jackson wearing a dress and a hat with a long blonde braid attached to it, one that looks a lot like Target’s Frozen Elsa hat.
