People simply miss the spirit of Islam. God wishes for us convenience not hardship (2:185), but by refusing to understand that God wants to help us slow down, practice self restraint and upgrade our remembrance of Him, they end up making the religion difficult to enjoy and appreciate. God only orders us not to eat and drink (2:187), and surely He does not want us to suffer while we are it! Just doing something because He said so (whether we need it or not), is Submission to Him (Islam). Saliva is not a food or drink substitute. So avoiding swallowing saliva, a biologically natural product of the mouth, and deliberately making oneself more thirsty or believing it constitutes breaking the fast is a false notion. If the idea is to suffer the hardship of heat and thirst during Ramadan as some people think, why do they sit in the breeze or an air conditioned room which definitely reduces thirst?

Watching TV also does not nullify a fast. If TV is okay to watch in the rest of the year, it is okay to watch during a fast. Like with everything else, believers must only see that nothing in life distracts them from the remembrance of God, be it TV, or business, family or anything (9:124, 24:36-37, 31:33, 35:5, 63:9).
