Everyone has a different opinion on what music they like. For example, I personally dislike the music in your signature but I do like Glitch Hop and Electro. That doesn't mean I need to argue with every other person who likes another style.
In my opinion, Bronies need to grow up instead of watching cartoons that were intended for small children. Again, that is my opinion and I have the right to express that. You also have the right to express your opinion but there is no need to argue with other people's views.
Like I said earlier i do not watch little children's movies and shows i just like a characters from one of the shows which my little sister likes. She is a shy cute character that is the same as you liking a character from a book that you read because you like how they act. I do not watch the show, I just like the character.
