I think you are mistaken in assuming Trumpers wouldn't "act out" their hatred for conservative Christians. They are driven by anger and they hate anyone who dares to oppose them. On more than one occasion at dinner with friends who are not Christian they have voiced disdain for the "social conservatives" who don't understand what's important. I've tried explaining that for me and fellow Christians the value of life and protecting the most innocent is paramount. They just shake their heads. I have asked them if they have an objective source to instruct them in their morality and to build their laws on, or if it is just will of the people that determines what's right and wrong. Trumpers usually respond it's the latter.
Holy drama queens, batman!
No Trump supporters here, and none of the many I know personally, hate Christianity. Or any other religion, for that matter. Most likely in your own life, you are seeing what you want to see when you talk to pro-Trump folks. The Social Conservatives are starting to sound like the Al Sharpton/Jessie Jackson "we're under siege and underprivileged" baiters...and its absurd. Drop the Victimology card and move forward.
For the record, Trump supporters don't hate Islam, Hindi, Judaism, Christianity or Rastafarians (etcetera) either....but would rather none of these groups seek to make government a branch of their belief system. Someone's faith is a personal thing, and by its nature works to shape our political views...and its important that we respect people of all religions....but we must do so without trying to set one above the other.
And let me help you out on one key point you mentioned....there IS no objective source that can instruct you on morality. This is true because "morality" is not a Christian ideal any more than it is a Buddhist or Shintoist ideal (for example). Point being, we all have our subjective and personal sources that inform our ethics and morality...and that is as it should be...not sure why that should really dominate a decision about who we vote for in this primary.
So by all means, vote for the man/woman you think is the best option available to lead the nation....but lets not pretend that Ted Cruz is any more a "moral" man than is Donald Trump...even Christianity will tell you that it is only God who can see what lies in a man's heart.
