If the topic is about coffee, you may post your critique of coffee (e.g. "Coffee is better without sugar.") but you're not allowed to attack coffee (as a subject matter, e.g. "Coffees suck and soft drinks rule.") nor are you allowed to attack those who adhere to it (if it were activities that can be partaken in, e.g. "Coffee drinking is for idiots, soft drinks for the win")
