Welcome to the Forums, I'm pretty relieved that you have taken in the newer generation of ponies with a kindred interest. Back in my earlier days as a filly, It was kinda hard to grow up, when people knew you watched the first generation ponies, and occasionally ridiculed you. However in due time, It becomes an increasingly strong fad with those morals and songs clinging in your head, you learn to forget about the others whom dislike you. Making a lot of friends becomes easy, and in the end, those who know you and accept you for who you truly, are truly the dear ones to bond together for life.
I bid thee welcome to the forums. I'm relatively new myself being somewhat akin to My Little Pony before terminology like Brony and Pegasister existed to me. Alas, worry not, I'm sure you'll come to enjoy the company of your fellow ponies! Stride with pride, and just be yourself!
