No i don't think Niall is an outsider. He is loved sa pamamagitan ng all the boys and they are very good friends. Some people may not like Niall and think that if he wasn't there the band would still work perfectly. But i think that he is the best one in the band and he has an amazing voice, without him the band would be nothing.
No, I think Niall is amazing. And all the other boys are also amazing and there all friends! And it doesn't matter if his Irish and the others are English. There all British! So no i don't think he is an outsider!!!!!
