All of our wedding customs are original and copied by the goyim, including, as per the Talmud, the throwing of rice or grain at the Choson and Kallah.
The only exception is when the Choson and Kallah come into the hall together. Our current custom is entirely fake and meant to be politically correct to appease the more modern among us and it distorts the emes way of starting out in a new marriage together.
It had been the custom for Yidden going all the way back, that the Choson walks into the hall handcuffed to the Kallah to show everyone in attendance who is really boss. I feel there would be far fewer problems if we reverted back to this custom as the Kallah would understand early on her place in the marriage.
