There's levels.
1.Liking the show
2.REALLY liking the show
3.LOVING the show
4.OBSESSING about the show
5.TALKING about the show every 5 minutes
6.YOU ARE THE SHOW. IT REPRESENTS YOU AND YOU REPRESENT IT.
I personally am a number 3. Mellow, but I still love to talk about it. When it comes to things like videogames, I am a number 6. I KNOW I annoy people in real life, so I am sure people that are one with MLP know that they get on people's nerves sometimes. I feel like when there are too many people with a level of number 6 in one place, it gives the fandom a bad name. Heck, it gives ANY fandom a bad name.
I stated this before, but I will NEVER dye my hair to look like one of the mane 6. I will also probably never go to a convention. I respect people who do, but I just can't imagine being in their shoes.
