Many that believe in science and evolution are also believers in God. Many that believe in science and evolution enjoy discussion of beliefs.
However, Young earth creationists are completely intolerant of any evolution being discussed.
Let's correct your statement.
While some young earth creationists are completely intolerant of any evolution being discussed, most are intolerant of evolution being discussed to the exclusion of any other view.
And I will add, from what I see in the media, it is far more the case that evolutionist are the ones intolerant of any other discussion.
