So I realized I have a certain bias against gaming.
What do you have against gaming?
I just don't enjoy gaming, is all.
Well, there's nothing wrong with that!  You should feel free to enjoy or not enjoy whatever you want.  Just don't think poorly of others for doing things that you don't personally enjoy!
Sure, I never though poorly of others for things I don't personally enjoy.
That's positive attitude to have. If the activity is relatively harmless when done in moderation, it would narrow-minded to judge someone because you don't think it's cool.
