I partly agree with your second point, but the thing is that you have to figure out the person does not mean what they say - that’s the point. If you state the sarcasm explicitly it is not really sarcasm. And while in some contexts it can be hard to know for sure whether something is sarcasm, I do not think this is a problem, and it is more often than not, like in this case, rather obvious.
Also, for the “antifascist” thing to work you would have to take everything everyone says at face value to make sure there are no ambiguities. So if made a joke withut the “/s” or “/j” or whatever you would assume I am being serious? Honestly, making our communication more primitive just so that fascists are marginally easier to spot(I mean you can probably figure it out without the “/s” anyway) is, in my opinion, absurd.
