I assume that incest rights, and incestual marriage rights, is something you are very passionate about. Nothing is stopping you from promoting incest advocacy, forming incest coalitions and groups designed to promote incest rights awareness, and organizing incest pride parades. Gay people fought for their rights to change legislation they deemed unfair to their humanity, and you are free to fight for the rights of your incest interest group. I wish you luck in your fight for your people, and brethren. I look forward to the coherent pro incest arguments you'll make in the future.
