There are some signs or opinions a lot of toxic stans seem to have.... I've named a few, but if oyu can think of any others for all means tell me!
1. You shouldn't call an idol by their stagename. If you do, you aren't a REAL fan. (Like WTF, but I've seen it quite a bit...)
2. You should only ever stan 1 group, because if you stan more, you aren't a REAL fan. (They really are going willingly blind and deaf aren't they)
3. If you have a bias, you aren't a real fan, because real fans love ALL of them equally! (Not as common as the other ones... But I've seen this one aswell)
