You weren't just asserting a preference, you were putting down that which you don't like repeatedly. Whether one chooses to spend their time crocheting or watching TV is a strictly subjective value judgement. Is it better to laugh at a Seinfeld re-run, or Louis CK live? Better to watch Game of Thrones or read the books? Purely subjective, there is no superior choice.
Are you trying to be smug? I have no idea if that's your character type, my point was that what you said comes across as smug. It sounds culturally elitist, as though TV is for the little stupid people (I know you didn't say those words).
I think it can be argued that one is a more intellectually stimulating option, while also being entertaining. The fact that people prefer the more easily digested option might be partially due to the effect of advertising and what makes the wheels of capitalism spin.
