Can I consider myself a serious gamer?

I like to consider myself a serious gamer. I love games from grand theft auto to God of War to Leisure Suit Larry to Sims to Burnout Paradise to Heavenly Sword. But I can't get into Shooter games. I suck so bad at them and practice doesn't help. lol. So can I be a serious gamer without liking shooters? it seems that any serious gamer I hear of love shooters.
