Does perspective to someone else break first precept? Recently I meet a monk, I noticed that he has perspective to politicians that what they doing wrong, they are wrong, but I seem he speak a lot about politics, OK. But he also being little rude even when he was telling an incident he used some 'rude' about politician. So when I tell this to my uncle he said 'When he's monk he should not be rude to someone or harm even by "Kaya (Body/Physically)", "Vacha (Talking)", "Man" (Mind/Thinking)'. So does it break first precept? If you caught me doing wrong(Killing, Stealing, Inhumanity) and if you make specific perspective to me for lifetime does it break first precept? Thinking wrong about someone else for what it is (Thief, Terrorist, Murderer).
It certainly doesn't break the Vinaya rule against killing (which says it doesn't count as &quot;killing&quot; unless somebody dies, plus other conditions).
I expect your uncle is right to say that he should avoid being rude; and even talking about politics at all could be considered questionable behaviour.
I haven't seen any hint, though, that the first precept isn't meant to be taken iterally; for example:

pāṇātipātā veramaṇī：'abstaining from the killing of living beings'，is the first of the 5 moral rules binding upon all Buddhists
(Buddhist Dictionary by Nyanatiloka Mahathera)

If the behaviour is wrong I don't think it's because it breaks the first precept -- instead I think it would be because it's not Right Speech, or something like that (e.g. not friendly).
