Raising a kid as a vegetarian could be seen as imposing your own opinion on him. But pushing the child to eat meet is no different. I think the ideal solution for vegetarian parents is to provide the kid a healthy and balanced vegetarian diet at home, without making meat some sort of a taboo or prohibited thing. The children should be able to decide on their own whether they would like to try and possibly eat meat or not. Of course, parents should be there to educate their kids, as much objectively as possible, with as many information as possible.
