I have no problem (well a little, lets be honest) to using the term helles. It does translate to light. However when you call it a Munich Helles, you are specifically calling out a beer to a certain region, the region the name is modeled after. So in my mind if you do this "call out" it should be as if you are sitting in that region enjoying the local fair. I can say with 1000% certainty Munich helles are not fermented warm and with a kolsch yeast, not to mention other details, you would literally be laughed out of Germany if you told them this. So again to me it's false advertising, because if I bought this kit/brewed this recipe it would not be anything close to the beer from Munich. People would make money off me, and I would be left with a beer that is not stylistic of the beer its modeled after. Thats really where my issues lie.
But at the end of the day, it's really not a battle worth fighting, because it doesn't really matter. It's just stupid beer.
