My collegues at work voted against a clean proposition and I am very dissapointed in them?

I even don’t want to say "Hello" to any of them. I know that hidden personal interests were involved, but the voting against slows down the productivity (esspecially mine, allthough probably nobody thought of that). Now I hate everybody.

Should I still make the usual kind face, and the hellos, or should I show the "traitors" that I don’t respect them anymore? They have a higher position, but the cases when we are pollitically in touch are very rear. Untill then, I’ll "catch" them hierarchically.
The proposition was not mine.
Also, I hate them not because they DISSAGREED with me, but because they negatively affect productivity of all company, and promote personal interests as a priority.

Well at least you’re handling it in a mature and professional way. Maybe if you held your breath and stomped your feet they’d come to see your side. How dare they not consider whats best for you, personally, when making their decisions.
