I am so sad

[Alex K]

I'd be real pissed if I were her

She's allowed to be.  I am not seeking tact in life. Never have.  I don't go the way of least resistance for it never solves anything. 

That's great. If you think it makes it more likely for her to listen to you...

My eyes are prolly dead too
Most people tell me I look high
I'm not saying that I'm not, but it's annoying

That is exactly why you shouldn't judge a book by it's cover!
Unless of course it's got a cross on the front of it. Then as Min says, it's only useful purpose is to wipe your arse with it.

I just logged into my old Facebook account to see my sister.

Her eyes are so dead and she has all these postings of religious memes that are the antecedent to logic.

I posted on her wall of how I logically felt about how she is leading her life.  I doubt it will do any good.  I honestly believe she is too ingrained within the ignorance of religion.

Talking about religion can be a very difficult and uncomfortable thing to do. 
I don't want to be the one to tell my loved ones that there's no heaven and hell, and that all the suffering they've had to endure during the course of their lives had no significance whatsoever.  I don't want to be the one to tell them that life is unfair and that there is no god who'll make things right when they die.

Would you prefer to live a painful life based on reality, or a comforting one based on fantasy? 
Personally, I'd prefer the latter (if it was still a choice for me). Sometimes, I wish my eyes had never been opened to reason and the burden it carries. Have you ever heard the saying "ignorance is bliss"?

Please, think carefully before you intervene in your sister's beliefs.
