This has been going on a lot lately in my country. Usually, in a discussion where some antisocial behavior of an organization is being criticized, a supporter of the organization, usually a member of the major religious group, makes an argument that the opposite side is fascist and is oppressing them. They argue that despite being the majority, there is a tyranny of the majority. In fact, the arguing organization itself is itself oppressive, such as in the historical exercise of power under fascism. They allow no scope for political dissent, anyone opposing them is termed anti-national, and critics are accused of hate speech and being against freedom.
So what sort of logical fallacy is this where political entities level accusations against critics usually with an almost non-existent logic? For example, a fascist-in-action calling the anti-fascist critic a fascist.
