it's 100% a joke that's meant to get a reaction and be offensive to these 2 groups. Nobody cares if it's a strawman or not because it's not meant to be a logical argument or a valid representation of reality
A strawman argument is when you refute an opponents argument that they didn't make as a method to try and beat them. This isn't a debate so that term doesn't really begin to apply here; however if you were to look at is one big debate with the ENTIRE feminist/islamic movements on the one side and the artist on the other side then this still wouldn't be a strawman because when you inflate the scale up that large you actually do get Islamists and feminists that make pretty much all the points represented in this.
If anything it's closer to an ad hominem against a large group of people however that still doesn't really apply because once again, this isn't a debate. This is a satirical cartoon musical meant to exaggerate the logical in-fallacies of, and draw a connection between two different sociological sub groups of society.
The guy isn't pushing an argument or trying to use this attack on their character to say we should do something, it's just a straight up attack on their character based on the kinds of **** they've pulling over the years.
How convenient that we don't live in a world where it is not a strawman. Because that would be a ****** up world. ...And our world is fine. ..It's not ****** up. ..it's fine.
