I was trying to find an existing thread to read others' thoughts on this topic, and also, to let out the accumulating negative thoughts in my head. Not having many physical contact nowadays make myself have some imaginary arguments in my head that slowly driving me nuts...
Just like TheDivineOne, I always had problems with the "God complex". It was not an edgy turn during my teenage years (when I found great pleasure in black metal bands and their blasphemous music), it started as early as childhood. I was always surrounded by several Catholics. The fact that most of these people play positive roles in my life, does not change my general hostile feelings toward the idea of God. However, I noticed it's not really "God" that irritates me, it's how religions and people talk about this being. And it leads me to my main problem: even if there's a "thinking" god-like being behind everything we know, why am I supposed to worship it? I've never worshipped a being like a god, yet I consider myself spiritual and also, my life can move to good directions without using prayers. Basically all my life, I've tried to find strength in myself, my thoughts, the Higher Self, or anything but not in a god-like being. To me, the whole idea of worshipping a spiritual entity is a big 'no'. It goes against my feelings because I have the suppostition that things happen and evolve around us even if we don't put effort into prayers, worshipping, and such. I imagine everything we can't sense with our normal senses as something very abstract, something that works as cold as algorithms, and not something we can personalize or please through prayers or church visits. If I get something people would call "God signs", like long periods of synchronicity or fortunate events, I only pay attention on them or follow these signs like they are traces in a crime case, and I usually believe this approach is enough. I won't fall on my knees and murmur prayers to a god and go sentimental about how "blessed" I can be. It's important to appreciate what we have in life, but I still don't get why am I supposed to worship a "God" for them.
While I try to accept that whatever I think and feel, it won't change the world and my Catholic friends will remain Catholics, they will worship a god and his son. And these people can be really great people, so don't get me wrong! I may have some past life carry-over feelings that causes this whole discomfort, but one thing is sure: every time people let out their god-related thoughts in my presence for more than 10 seconds (and they usually aren't interested in my own beliefs, since I don't belong to a church and a dogmatic religion), I feel like the cat that's fur is getting stroked backwards: I want to hiss, scratch and bite.
Plus, it certainly makes for more pleasant conversations.
