So you don't know how to read? You know what? I am going to explain this even though you think it's some karma conspiracy (which only got the 63 upvotes) Older people are at a significantly higher risk. People are hoarding stuff like toilet paper even though there is no evidence that toilet paper supply chains are going down. The image is pointing out that selfish people are clearing shelves of basic supplies instead of getting whag they need. This grandma will have to come back out to restock at a later date when the virus is much more prevalent and thus put her in danger.

If you're against people getting karma, likes, internet points, then get the fuck off reddit and social media. This person is posting an image that evokes an emotional response that will get people to rethink their "every grandma for themselves" mentality. If you don't get it at this point then you're a lost cause.
