I personally hate it when people make a huge fuss and have to declare to everyone that they are a vegan/gay/freegan/scientologist/jehovas witness/athiest and proud, demanding recognition of whatever they are when clearly no one cares.
i dont think they make a big fuss but it does hurt your ears a bit when instead of "how ya doin?" from your mate you hear "you feeling fabolous silly buns?" and inestead of "thanks for cooking a dinner tonight honey" you hear "i dont eat meat or anything that came from something with a pulse"
