It may be difficult to find evidence to back up the viewpoint.
Explanation:
Finding evidence is key, so if you are trying to support an unpopular view point it'll be very tricky to find some evidence, because it wont just wedge in by itself. And, if not many people to support it, i doubt there will be many articles that disagree, so finding something to work off on will be merely difficult in the beginning, but not impossible.
