The way NORMAL people play (and I consider myself normal) and act is to have a bit of respect for the person who put out their time and energy to provide some entertainment in the form of a game.
It might have been family game night or DnD, but it makes no matter. Poker, charades, roleplaying...
you may not have hosted the get together, but the least they could do is respect your input.
I hope you find a better or have a better group to game with in the future.
