My current pet hate: people/websites that spout ridiculous pseudoscience claiming that they can cure cancer/type 1 diabetes/any chronic illness with a simple, natural solution... I don't understand how anyone can actually buy into this ridiculousness. Do you not think that if there was a cure for cancer out there that 1) all scientists in the field would be interested to test it, write on it and tell the world about it, and 2) all pharmaceutical companies in the field would be interested to harvest this cure to sell and make money? It makes me angry that ill people and their families are mislead for the sake of promoting an ideology that clearly doesn't have the extent of benefits that you're suggesting (and usually comes attached with a price tag in addition to false promises).
Anyone out there tonight? Tell me your pet hates.
