What Quinn said wasn’t fair.
No one but that person knows exactly how they feel and what they are going through. There are just some things someone just can not properly comprehend if they haven’t gone through it themselves.
To say he was selfish and didn’t need as much support as his family was out of line and ignorant. 

Way to give me one more reason to not like Quinn’s character, Glee writers.
