Activate, you are doing a fair amount of patronising yourself, and being a tad aggressive towards stoats whilst doing it. She has a different opinion, and is allowed it - it's a talkboard, you invite different points of view, and it is expected that they will be discussed.
I am not a huge fan of any homework at primary level, speaking both as a parent and a teacher. But 'find out' homework I find is more enjoyable than most, and usually does generate lots of excitement and enthusiasm for a topic. The skills described are part of the curriculum, and the follow up lesson stoats described is excellent for speaking and listening, reading, writing, ICT, etc - and I say that as someone who regularly has to judge lessons, and has my judgement judged too.
If you don't want to do it, don't. Some children will get lots out of it, some don't. In many schools, teachers are obliged to set homework regardless of their standpoint on it, and as homeworks go, it's quite valuable, imo.
We could try and discuss it without the sneering, I think.
