Does specialty beer ruin your taste for commercial beer or is it just an ignorant bias on my part?

There is no such thing as "brings my own 6 pack of high quality Budweiser"

To be honest, this is a ridiculous debate. You like whatever it is you like. Some people like craft beers, some people like Budweiser. It's a matter of personal taste.

Same discussion can occur with wine or whisky(whiskey) or even bread.

I like prefer craft beers myself, but there is nothing like an ice cold Bud/Coors after you've finished mowing the lawn on a hot/humid July afternoon.
