That's ridiculous to be fair.
I am, to a certain extent, just messing with a red on the forum.
But why is it ridiculous? There is an underlying statement there. Many of the people blurting "don't by the sun" weren't of an age during the incident. They don't actually understand the significance or the reasons behind it, they are just tagging along because it's the trendy thing to do, "DON'T BUY THE SUN" like it's some chant at a football match. That's the wrong reason to support any cause.
