Not every believer is a creationist, nor does every creationist blame earthquakes on gay marriage or believe the bible is a history book. By tarring them up like that, you are effectively insulting them by implying all their most extreme examples of faith are linked and hence medieval - and by extension, you're basically implying all Christian beliefs are also medieval.
In fact most christians are not creationists , and most christians have more modern views of the world than that and also about LGBT rights and evolution, most of the groups that support middle age views are evangelical from the USA, the ones that twist the bible and pick what it interests to them, which happens to be the ones that promote most lies about climate change and i can't hear/see the others groups trying to stop them.
