DSIL is 34 weeks pregnant with first DC.
A few weeks ago her and her DP announced the planned baby name.
The actual 'sound' of the name is fine, but it is heavily associated with something which DSIL and her DP were not really aware of. They have been made aware of the association since (as it's pretty common knowledge- not sure how they hadn't heard of it tbh!) but are of the opinion most people won't make the association. DH and I are of the other opinion that most people will definitely make the association, it's not a good association, and genuinely worry that it's not fair to give a baby that name and it's fully possible it could lead to bullying when older.
Whilst DP and strongly agree on the huge issue with the name and agree it's unfair to lumbar a baby with it, I don't think DH should say anything. DH thinks he should have a proper talk with her about his concerns on the name and why he doesn't think it's fair to give to a DN. I think nothing good will come and we should stay quiet.
(So far we have said very little about it. We were notably shocked when told what it was, and clarified 'X' as in X'?? But other than that have nodded and smiled).
