If a table is playing really friendly, is it bad etiquette to shove all?

[rickyponting]

if everyone played 'nice nice' poker would be a very boring game. you're not there to make friends, you're there to have fun and make money, that's why you play. No its not bad etiquette to move all in here.If people want to play nice they can play the limit tables. No limit is a ruthless game!
