Yes, I would attend. I’ve never placed politics in front of friends and family and I doubt I ever will.
This is not about politics, it is about good and evil, right and wrong.
My Father was the son of a Baptist minister and was brought up thinking the Catholic Church was guilty of all kinds of sins. When his daughter married a Catholic boy, daddy would not go to the weddding. Mother and the rest of us did go.
My Mother had and extraordinary love for her children even by Mother standards. I got to thinking about it and even with Mother’s love I know she would not have attended a marriage between one of her Sons and another man. I can recall her reading her Bible by the window every evening.
Fortunately she never had to make such a choice as her Sons loved girls and her Daughters loved men.
Interestingly my Father finally got over his Catholic Son-in-Law and thought the world of him before he died.
However, as I said at the start, that is your opinion or choice to attend it and you have the freedom and free will to do so and I respect that.
