The common misconception people easily make about DF is that you'll magically get people with your own play style, or if not, the others are wrong. However this game has many different styles to play, most of them as valid as others. While 'to the bitter end' is a valid game style, so is 'no hopeless attempt'. DF is generalizer and while you might luck out with having majority of your preference, that's not always the case. I have got annoyed when I get on low level group who want full clear if I just want to pass. The same day on another class I was leveling I got a quick run group. But while that annoyed me, I was not blaming the other players for it as random is what you get in DF. If you want the whole group to be of similar preference in style instead of yielding to majority of what you get in DF, use party finder instead. PF even lists "to the very end" (not exact wording) as one of the search conditions.
