You've gone to hetero weddings where they screamed praise for heteros, promoted barbestraights, and forcefully put straight scarves around the necks of guests? Wow!
I've been to weddings that was explicitly promoting heterosexual only marriages and straight weddings with scarves at the photo booths. I've been to weddings that explicitly stated that women are subservient to men.
Edit: In fact, the modal wedding I've been to treats the bridge as property.
