There is a new symbol for marriage equality being displayed for the movement to utilize, it is the white knot and if you are attending any demonstration for equality be sure to wear one.
The White Knot is the symbol for marriage equality. It takes two traditional symbols of marriage—white and tying the knot—and combines them in a simple way to show support for the right of gays and lesbians to marry. All loving couples deserve the same legal rights, benefits, and respect that civil marriage bestows.
