You're certainly welcome not to pay the licence fee and not watch TV, but spreading lies about how supposedly bad the British TV system is is disingenuous and perpetuates a silly North American myth similar to that about British food or teeth.
Now, I'm off to clean myself as I've just defended the licence fee, something I'm not entirely keen on myself ;-)
All you're buying for the license fee is a break from the constant stream of anger and threats from the TV Licensing people.
Thanks!
However, the TV licensing authority operates in a paramilitary fashion, so they try to scare you into paying for a license even if you don't need one (as the GP describes).
Still, though, I get angry letters from the TV Licensing people several times per week. Different ones each time, with new creative threats about what will happen to me if I don't disclose the hidden TV they know I must have and pay up. If they'd simply put the people writing that stuff to work making television programs, they might be able to come up with something worth watching, thus prompting me to buy a TV and pay them money.
