Have you ever had an opinion that though minor and non-offensive (no racism, homophobia, sexism or any other offensive material here please) that could still be controversial?
For me, Zubat is one of my favourite Pokémon and I don't really understand why it's so hated by fans? It's probably because when I was a kid, there were two pipistrelle bats in my garden that I would watch at night and it and later Goldbat was one of my core members in my original playthrough of Pokémon Blue.
However, my favourite Pokémon has to be Bellossom, one of the fully evolved versions of Oddish:
Why? Well, In Pokémon Silver, I screwed up royally during my first time fighting the Elite Four and lost all my Pokémon during the fight with Will except for Bellossom, with no way of reviving them because I forgot to buy Revives. Somehow, I beat all of them with only her and ever since, I always try to have a Bellossom in my party.
So what are your minor and non-offensive but controversial opinions?
