For those complaining this is aimed at children because it's promoting something eaten by children: it absolutely isn't.
It's aimed at the family shopper - usually the female parent in a family. You can't even target ads at people below 18 online so unless your kid is lying about their age online/ using your account, they won't see it.
It is an ad that appeared as social content, not on TV. If you're letting your impressionable child on instagram you've got bigger things to worry about than a man in drag.
Finally, people comparing drag to blackface is abhorrent. Drag is almost exclusively performed by the gay community as a form of self expression and rebellion against a society that confined them to traditional ideas of masculinity. It's a traditionally marginalised group taking the piss out of themselves, not women. The venn diagram of 'drag is blackface' and 'white lives also matter' is a circle.
If you find it offensive that's absolutely ok, you are entitled to feel how you feel. You are also entitled to not find it funny and you can even stop buying McCain products as a result of their marketing, just like I'll by A TON of potato smiles for the freezer this weekend to offset
. If you're going to take a stand over this though there's a TON of other brands who love and support the gay community you'll also want to boycott, drag, trans and all... unless this is just a fun thing to get frothy about on a boring Tuesday afternoon and you're actually not really that bothered.
