Well, I would say that here in Christian Forums you have not found mainly what Calvinists claim
And in my opinion there are different groups represented for different issues. So, in case you have only or mainly been finding Calvinist representations, may be this is because of your way of searching.
But it is possible that people can pay Google to favor their stuff. So, just in case certain ones claiming to be Calvinist have payed to promote their sites, you could need to use a different searching method, in order to bypass that.
Also, not all people claiming to be Calvinist might agree with each other about certain things. And people can misunderstand what they are saying.
But I think I have gotten more from the Bible, than from a lot of people who are mainly comparing their stuff with other people's stuff
Well, even if Calvinists were to be wrong, this would not at all be because others don't agree with them! Jesus says many will be deceived and lead many astray. So, great numbers is not at all evidence that so-and-so must be right!
