Hmmmm, I would not be close friends but no matter what a person believes or does, if they are in need, I would be there to give a hand or help if needed. Not to enable their beliefs but to help in a physical sense if ever necessary & called on tp help. I have stopped to help many people who have not been of the same beliefs ir philisophy as me. I will show kindness & caring to anyone in need but that doesn't imply a close friendship. That does require sharing common beliefs & values.
Would you walk by on the other side of the street if they were laying there bleeding or would you make sure thay got the help they needed?
Kindness for someone you disagree with is different than a friendship byt friendships come in many different levels from intimate sharing with someone to acquaintance level.
