Welcome to the Arena. If you like to collect brushable plastic horses, then you're a My Little Pony Collector. Let's leave gender-perspective terms out of it. :-p
If you don't like the brushable plastic horses, then you're a Toy Collector. Again, no need for gender-perspective terms. :-p
We have collectors who like G1s, G2s, G3s, and G4s. Some people only like certain generations, some like them all. But they are all PONIES! After all, with 30 years of toys being produced, there's something for everyone to like.
