"why folks have this need to attack Christianity to the exclusion of others"
Who's excluding others?


"What is it to you what I believe? "

Absolutely nothing at all... but when you want the myths of those beliefs to be taught as science... or you wish to use those beliefs as the basis to make laws that interfere with what I can or cannot do in the privacy of my own home with another consenting adult....   Or when you feel the need to inflict your beliefs on children who do not have the antibodies necessary to fight off such an infection.... Or that you are justified in bilking poor, lonely or ignorant people out of their hard earned money....

Then I have an issue with what you believe


"to believe that Jesus was a real person?"
Believe what you want... it won't make it fact.... I can close my eyes and believe that I can hover all I want.... or that I can walk on water.... It won't make it so....
