Celebrities this week have taken to social media to encourage others to wear masks and, in the case of Tom Hanks, shame those who have been refusing to comply with this basic health and safety guideline. In America, wearing a mask has turned into a contentious debate. Some are holding onto the belief that it’s their right not to wear a mask, while others point to it being a social responsibility that will save lives. Now, Hollywood A-listers, musicians and athletes have joined the conversation in support of masks.
