YANBU!
I was fully vegan a few years ago, fell off the wagon and now got back on it again.
Really recommend checking out Colleen Patrick-Goudreau, she's a wonderful vegan chef in the US. She has a huge catalogue of fabulous podcasts and she sparked (I think) the concept of the 'Joyful Vegan'.
In her podcasts she has masses of great tips on everything, including how to entertain and not be a 'pain' at social gatherings, school events, work events etc, and how to be the 'vegan in the room' without being preachy.
Her main tip is to take along wonderful vegan food to dinner parties etc, which relieves the worry of the host, and also shows everyone else that vegan food can be delicious. She also points out that 'vegan food' is often just food! Vegetables, rice, seitan, etc, dips, hummus - everyone eats them, so its not as though a host / friends have to suddenly whip up something unusual or unfamiliar.

On the contrary, if you love how vegan feels, and are unapologetic, you are likely to become an inspiration to others, not an annoyance.
Just remember that everyone is at a different stage in their life - you, like me, were possibly a meat eater once, so it is not for us to judge people, but to provide positive information and be a positive model for what a fabulous life change this can be.
Go for it!
