Neither does black cultur or asian cultur.

Fine.

But let´s not forget that the othering is a political tool used by everygroup on the political spectrum. In the US right now "illegal immigrants" and "magats"as example.
The second on being way closer to "bugs" in the dehumanisation department.

"To change the point."

Which is a literal propaganda tool. To add or emit information to change the tone.
Trumps: "They are eating cats and dogs comes to mind"

(also dog tastes good tho)

Fair enough, but the issue here is that the "bugs" are really not human.
As such there is no such thing as dehumanisastion going on.
The threat from the bugs is also not imaginary so no demonisation is going on either.
Which means the (CRITICAL) part is non-existent.

Militarism =/= Fascism.
