I'm going to suppose that can be broadened into beliefs in general.
True. There is even a saying in Dutch "He is very religious about it"
Tell us, if you care about what other people believe -- or don't believe: why do you care? What does it matter to you?
Interesting topic. Thanks.
Why do I care (how does this whole care thing work)?:
IF someone gives you a knife saying "cut out your heart" THEN you won't do that
IF next he gives you the knife saying "cut out my heart" THEN you might have done so BUT with above experience empathy develops
IF next he gives you the knife saying "cut out D.T's heart" THEN you might be tempted BUT scared or even wondering if the person has a heart
IF next he gives you the knife saying "cut out Superman's heart" THEN you might do it, as it is just a virtual reality BUT it might impact your empathy
How much you care has everything to do with the level of empathy and compassion you have developed; if you developed your "feeling"
The further away the other is the more difficult it is to feel empathy.
And if you train yourself in the "virtual world" probably you become so in the"real world" before you realize.
Having people watch films depicting some "new normal" is a known fact to influence and control people (hence all the ads. and Hollywood movies).
If you watch things (or the other senses) then before you know you develop these feelings.
Why do I care what others believe? What does it matter to me?
I care that all are free to believe as they like, and I care that others don't impose on me, and due to this feeling don't impose on each other. When I was young I was not allowed my feelings, hence I developed the feeling that it is important for me to trust and own my feelings. This is something personal, hence I care to not cross these limits with others.
If others decide to choose a path that I have experienced as very painful, then I am motivated to warn them, but I also realize from my own experience that when you go very deep in an emotion that afterwards you can gain a lot. So, sometimes it might be better not to interfere, and let someone "drown a bit". And when asked "to care" then it usually is the right time to care.
Why do I care what others believe?
If you specifically ask about "beliefs" then I am fine with whatever others believe, as long as they don't hurt me and/or others in the process. Again, when it comes to something personal then my ego might jump in and try to dissuade them, but the good thing of RF is, that I become more aware of this now, seeing so many different views, and losing this urge to change things or people.
Change yourself first if you want to change the world they say. Maybe that is just enough even.
