"You mean the ones that use to post here.....right, you are not saying everyone, like in everyone, right....?"

 I never typed the word "everyone" or in any way inferred "All", 100% or "Every" in any capacity.



"I mean when you say you are only giving you opinion, perspective, etc....
You don't mean to say, "Its the truth, and that is why you believe it......right?"

 I am not saying anything in this post is truth.



"Do you think anybody, or maybe everybody, only believe something without regard to it being true, or not?"

 I do not think everybody believes in something without regard to it being true, or not.  I do think some people do.
