Bulverism means to discount an argument because of the arguer’s identity, rather than reasoning the argument itself. For example, if a male made an argument against the idea of patriarchy that could be considered feminist, then it’s illogical to dismiss due to his gender and political identity rather than reason it..
This can manifest when you let other people label you, if they can dismiss you as just a _________ [insert blank] or perhaps if you dismiss your own reasoning based on an identity you hold about yourself. This is another benefit of logic, what’s right is right and if your holding onto aspects of insanity, insane illogical thoughts because you are a __________ [whatever] then a logical, stated (written) argument that is sound, without fallacies, is the truth — even if you’re a pink elephant dog hating nazi [or whatever you are].
