The Tasmanian Wolf was not actually a wolf , or even a canid but in appearance and habit he was similar enough to make the comparison apt.
The Tasmanian Wolf had a diffrent number of teeth , even some organs absent in the true wolf if there were any common ancestor it would have to be an ancient creature from before the development of the Mammalian characteristics common to the wolf and the mouse.
So the wolf is actually a closer relation to the rabbit than to the Tasmanian "wolf" yet the name, I would argue, is still apt.
The Tasmanian Wolf may be from an older stock and got no design tips from Europe , but it developed in convergent evolution to an similar size and shape , and a similar habit.
Not precisely the same , but close enough that it is more apt to call the creature "wolf " rather than the less apt tho more precise "carnivorous wombat".
Our main familiarity with Fascists was their aggression , their ability to harm , grow , metastasize and intimidate , the fine details of their philosophy are much less well known.
Not really many of us know a Sufi from a Shia much less do we have familiarity with the philosophy , politics and habits that differentiate the sects of Islam even than we do what differences there are between the political entity's of Europe, but when presented with a rapidly growing , furious , irrational , self righteous , ruthless , vicious , violent and widespread threat, we can be excused at ignoring trivial details and focusing on the commonality that makes the picture we are presented by Islamofascism seem so familiar and the opprobrious moniker seem so apt.
