You bring up a lot of good points I hadn't considered, and wouldn't want to impart on my child. I guess it's harder for me to see her character the way you do because my mother was so very different. I had been viewing it as sort of two-sided where a mom could either be like mine or be like Molly without considering that there were other options (I have limited mother experience). To me it always felt like she meant really well but had too much going on with such a large family. It seemed very loving to be able to cook well for one's family and spend time knitting them sweaters (I knit so I know the time/care that goes into it). I hadn't been viewing it as "how rude of her to use a color her kid hates" but more "how rude of Ron to be so picky about the color of a handknit sweater and the contents of a homemade sandwich" and for the robes "how ungrateful of Ron to snub his nose at something he knows his mother had to go out of her way to purchase. That money was probably needed elsewhere." My mother has never made me anything so I'd have been happy to get even a sandwich I didn't like, so long as someone had made it for me out of love, you know? She totally could've fixed the awful robes up for him though...that's a shame.

I also felt like she did a lot of her other more questionable actions from a well-meaning standpoint. She treats Hermione badly because she's looking out for Harry (and is maybe a little sheltered being a stay-at-home-mom so falls for tabloids because they're sensationalized). Same with how she treats Sirius. She regrets that he wasn't able to be better taken care of and lashes out (though she shouldn't; she's completely unfair here but I understand the motivation). As for Fred and George, plenty of good parents have a hard time seeing their children's talents as marketable and sustainable. Go to any art school and ask if anyone's parents support their life choices and even the ones with great parents will probably say "no" (source: I went to art school). I saw it as Molly wanting to make sure her kids would be better off and not poor or ever wanting for anything, so wanted them to have good grades and a career that could support them, something safe.

Now that you've called my attention to it, there are a lot of "Molly Weasley Things" I wouldn't want to emulate because I can see how they might negatively affect my child, and how he acts in the world. I actually appreciate that you've brought a very different opinion to the table that I hadn't considered. At the very least, I can now always think "What would Molly do?" and do the opposite, haha. Hope you don't get downvoted to absolute hell. These are a lot of good points from a different perspective than I'd expected and I liked it.
