Dining out in vegetarian places. Ethical?

Is it vegan-ethical dining in restaurants that also serve the by products of dead corpse? Such as eggs and cows milk? Should vegans dine in restaurants to appease their vegetarian friends? The Vegan Society (NSW) Inc that dine (are supporting) the cruelty involved in the cows milk and the by-products of the dairy industry restaurants. If the flexitarians, ova/lacto/pescatarians want to support these cafes of miseries so be it. Why are vegans contributing to these 'vegetarian' cafes? Why not support vegan only places? Why not dine in a pizza hut and have a vegan pizza or dine in McD and have a happy veggie burger? Is this ethical? Have you forgotten What is a vegan? Why a Vegan? I suspect some members have another agenda. Veganism is not one of them. Maybe the cheese and milk come from happy cows? The Vegan Society (NSW) Inc have sat on that slippery slide with Voiceless and Macro and appear to be endorsing free-range dead corpse. This is not what Donald Watson did 60 odd years ago when he disengaged himself from the vegetarian societyUK, fed up with the white lies and the vegan movement came into existence. Now the Vegan Society(NSW) Inc Australia appear to have gotten into the welfare bed with the 'pseudo' vegetarian/vegans. Is this ethical? Many of the vegan members should speak up about the way their committee members taking their society down that slide that you can not get off.
