Budweiser, Miller, and Coors is not beer. It's horse piss. Next time you want a *real* beer, I would strongly advice you check out your local brewery. Personally, I prefer Saint Arnold's and Shiner Bock.
Have you ever seen the television show "Bizarre Foods with Andrew Zimmern"? If you have seen many episodes of that show, then you will have seen the affable host eat intestines (the large ones, the feces-filled ones) more than once, where he usually cheerily announces, "When you eat this, you KNOW what you're eating!" In other words, once can taste the crap that remains within it. In other words, there are thousands of people in the world who regularly eat crap.
Likewise, you might also have seen the episode where he was in India, and he drank cow urine for "medicinal" reasons (as it was sold to him). In other words, there are thousands of people in the world who regularly drink piss.
That's why I never describe any foods as "crap" or "piss" any more, because people actually eat and drink those things, so it's just a flat out inaccurate comparison to make. Call a spade a spade: boring, weakly-flavored, low-quality, etc. (If you are a pompous food snob, then you'll spin boring foods as "subtle" or "delicate".)
Budweiser (an evil company -- go watch the documentary "Beer Wars" to find out why (if you like to drink alcohol and don't know what the "Three Tier System" is, then you need to see this movie for personal edification)), Miller, and Coors made traditionally weak-flavored beers. Most Americans are comfortable drinking those because they are not used to tasting strong flavors in general, and hops produce a very strong, bitter flavor that takes a while to build up a tolerance to and appreciation of. It just tastes horrible to people who aren't used to it. Once you are, then you start to realize wonderful differences of flavor between different types of hops (Cascade produces very distinct citrus flavors that are very easy for even a neophyte like me to pick out) that increase overall pleasure.
And that's what learning to appreciate stronger flavors is all about: increasing your pleasure and enjoyment of life. Don't try to shame people into conforming to your preferred beers (my current favorite is Southern Tier 2X IPA -- it is awesome). Invite people to try and perhaps they may take a chance and be rewarded for it. Sell it. But people generally have to be open-minded first. It's a tough sale to make. Most people don't like taking risks and most people harbor great resentments about being forced to eat things they don't like from childhood. It's literally emotionally scarring. I talked to someone once who said that he was afraid of trying something that he didn't like because it might ruin his appetite. I find that strange, because when I put something disgusting in my mouth, my impulse is to eat something delicious as quickly as possible to return myself to yummy mode as quickly as possible.
But people are weird about food. Very, very weird. Even me.
