I do agree that some people do get very hateful with people who disagree. I definitely don't hate anyone that disagrees with me. I care about the truth and want to help others.
I don't think you can have a saving faith in God if you don't believe God is creator, but there are lots of people who believe God created using the big bang and directed evolution to create or believe in the gap theory or the day age theory. I believe all of those are totally contrary to God's word, but that doesn't make their proponents unbelievers. That is not a salvation issue. (If you want my scriptural and scientific arguments, I can give them later).
In the same way, there are lots of different beliefs regarding the end times with some believing in a literal millennial reign (like I do) and some believing we are living in the millennial period now. Some believe in pre-trib, mid-trib, and post-trib. Only one can be right (I believe scripture clearly supports the pre-trib view), but these are not salvation issues and there are plenty of good Christians who disagree with me.
I do think that a right view helps you to live the life God intends for you and a wrong view hurts your witness and leads you to bad choices, which is why I am so vocal, but I hope my disagreements are not taken as disrespectful. I am passionate about God. I am passionate about truth. I am passionate about faith. Sometimes my passion may come across badly. I try to speak the truth in love as commanded by the Bible, but like everyone, I'm fallible and make mistakes.
