Agee with you, but I do have a sister that is a dyed-in-the-wool Leftwingnut.
Can’t really throw her away, after all, she is my sister.
Hopeful that she will one day see the light though.
Love your sister and avoid/boycott the dark side.
My sister is the same way- she’s no longer my sister- she’s a stranger- Jesus was very clear that our brothers and sisters are those that do the will of the Father.
