Ofc groups ,
If someone hates on a fandom , even if it's my fandom, it has nothing to do with me, the only thing that connects me with my fandoms is my faves
I don't take offence at some mean words being thrown at my fandoms because I haven't maden it to be my identity ....
Members of groups on the other hand are individuals who have to take in all the mean words being thrown at them on a personal level
Their skills, personality, looks, family, age - all of this is being under tight scrutiny of public and haters
It may and it does cause them severe self esteam and mental health problems to the point they may want to take their own life
...
I don't think hating on any fandom causes something like this and if yes , you should reconsider your devotion to your fandoms
