"Show me just what Mohammed brought that was new, and there you will find things only evil and inhuman, such as his command to spread by the sword the faith he preached." - Manuel II Palelologus
I don't believe in opposing anything. I believe in human rights.
If you can't accept the rights of others, that's not being imposed upon, it's just not understanding that you have no right to restrict others in the exercise of their rights.
Learning that lesson may feel like an imposition to you, but the point of exercising their right is they agree it and you are not effected, unless they're forcing you to be in the wedding.
if you don't like it, don't ride the bus.
