I'm getting very fed up of people saying it "won't cost you anything" to modify the language you use, in the way that they think you should modify it.
It takes cognitive effort to monitor what you're about to say and inhibit selected aspects. These are not always insignificant mental costs, especially if it's something that's been a common component of your speech and you have to monitor and prevent it all the time, even in your own home where you should be able to relax. Expending extra cognitive effort leaves you with less in your mental tank for other things you want to focus on, and can leave you feeling more frazzled, with a lower tolerance for whatever crap you need to deal with. Worse, we don't always realise when we're expending cognitive effort to do things, and end up feeling stressed and tired without knowing why.
Obviously we do need to do this kind of thing quite a lot in everyday life, modifying the words we use to fit the situation, because sometimes it's worth it to, say, not swear in front of customers, or avoid using slurs, but often we seem to be able to slip into a particular mode, which helps make it less cognitively taxing (work mode, talking to children mode, with mates mode etc.). Having to be careful about your speech because a child has got the wrong end of the stick about a ubiquitous pet name isn't usually one of those circumstances where it's worth the extra mental self-monitoring and effort.
An example of where it would be worth it: a friend of mine had no idea that the word she used for chilling out while stoned could be taken for (and probably originates from) an offensive word used for people with a particular disability. I mentioned it to her in the most tactful way I could and she was mortified, and has never used it since. I'm sure that initially there was a cost to her in monitoring herself and finding an alternative word, until the habit of using that word was gone, but presumably she thought the benefit (not risking upsetting people by using an ableist slur, not risking people thinking she was prejudiced) was well worth it.
But it is absolutely not cost-free, unless you place no value on your own mental work, effort and stress.
Incidentally, my mum calls me poppet. Present tense. I'm four inches taller than her, weigh twice as much, and am in my thirties. But I still like it
