And enforcing your morality on the internet does what, exactly?

State your intents at the beginning of the dungeon. Be firm, yet do not be confrontational.

You say you're not comfortable with a pull of x size, I am inclined to listen. You fuss, nag, and refuse to heal... You deserve every bit of the dismiss you are about to receive.

So many people get defensive and/or down right nasty when things aren't 100% the way they want (even if the results are similar). The bigest thing is: can you show you can compromise enough to get the others interested in trying to meet you half way?
