Well, they won't ALL be in one universe. It will be X-Men + F4. Both products of radiation, in fact!
And we don't yet know exactly how the films will deal with the emergence of the Fantastic Four. Maybe it will be a slower progression towards public acceptance.
The other thing is that in the comics, there has been prejudice against superhumans other than mutants. In the DoFP comics, the Sentinels turned on all superhumans in the end, not just mutants, and we see the graves of the F4 and a montage of dead heroes including Iron Man, Spider-Man, Hulk and Captain America. In fact, there has also been a Superhuman Registration Act in which all superbeings were targeted - it first appeared in the 1990 comics and then as part of the 2006 crossover Civil War.
Plus, Reed and Sue Richards have a mutant son, Franklin, who is part of DoFP in the comics.
All that points to the fact that it's not as clear-cut you may want to think.
In addition, there have been mutants in the Avengers, including Beast, Scarlet Witch, and they don't seem to face the same prejudice as Avengers as they did in the X-Men stories.
