Oh, yes, kinda.
IASP has (imho) a positive comment on issues, highlighting them, in the 'let's benefit society with this work' kind of way.
Drawn Together doesn't attempt to make a better world with it's impact.

Ofc (and by definition) one is better than the other.
But I don't think any bad thing should ever be a taboo.
If someone wants a racists in their work (it doesn't even need to be a comedy), that's fine, they were and are people like that. Its not arts job to tell/educate you about how bad things are bad (tho it doesn't hurt), as long as it doesn't hype them as absolutely good (ie propaganda-ish/as a commercial).

But let's bring Hitler into the convo, that's always fun - I do think its really bad how Adolfy (and Nazi Germany) became a sort of one dimensional meme in modern culture/knowledge, overly simplifying such a thing is bad af, those were people doing people things & we need to have a basic understanding of that.

Mr Ham being racists is still good for the knowledge how that is a person/character, how that sounds out loud, how that sounds a bit like your neighbour/politician/company/laws/traditions/etc.

So, Drawn Together imho still highlights issues by putting them into your thoughts, but it does not do a PSA about it (nothing actually bad happens to any of them as a 'moral story to learn from', even the moral stories there are an intentional joke, and consequences for other people aren't much more that a sidenote). Not that IASIP does a lot of that, but consequences are a bit more obvious (but not life-changing for the main chars).
