Oof, there are so many things I could say to this.
Imagine if you were to meet a very strong-willed Christian on a planet where all other Christians have been wiped out. Do you think they would care whether or not the Athiests hate them for being Christian? Do you think they would convert, or even take notice? They'd probably take it so lightly that it doesn't even affect them, what would affect them is the realization that there are not more Christians to share their love, they would still be negatively affected by what the Athiests think of them of course because it's a reminder of the absence of harmony that exists! So yeah, we care.
To take something personally is a whole 'nother issue. First of all, to be a person who takes things personally is to be a person that has themselves in focus because they are lone. When I say this I mean that there is no true support system or interconnected faith of any kind to the things in this world. When you are only focused on yourself you separate yourself from the world and all things that man connects to, and now you are a whole, versus being a part of the whole of a group or the whole of the earth...etc. With the threat of something so enormous as any characteristic at all being rejected, as each part of you is a lot more important when it's all that you have, you are going to question it simply to expand to the rest of the world again, to feels safely connected and less in focus, as you are alone and that is not part of our nature
Mizz's pink sock's example. If you are a lone person, with no support (which first requires complete truth to people, also), or spiritual connection (and i'm sure there are more connections) then if you walk out in pink socks and somebody laughs at you for it, you immediately feel very alone and unsafe, and then question whether or not you should switch your socks so that you feel safely connected to a support, if even so minor.
Did that make any sense... I can never tell if i'm just rambling
Yeah, I do care, but because it highlights the absence of those who will accept me and makes me feel like a piece misplaced from the rest. I'm still learning to lean that way and not take fault as I struggle to maintain the belief that a 'rest' exists, actually
