Actually, I'm okay if my ship isn't cannon, and I'm okay if the story goes the complete opposite way that I would hope it to. I'll still think my ship is cute and that's all I need.
Whats annoying is when people are trying to shove in my face the fact that my ship isn't cannon and being like "Haha, your wrong, you should feel stupid!" or like try to fight me over weather it's cannon or not. (Both of these have actually happened before and I literally had a panic attack)
A lot of people do do this though and it doesn't make sense.
