Spero, you have remained very calm against a lot of misreadings of your words.
If somebody has asked for opinions, they're expecting opinions. If I pointed out to an op that in a lot of areas Minnie is a slang term for female genitalia, I would not be saying that any Minnie cannot transcend the association or that it is even a reason for not choosing the name should you not be bothered by the connection. It's merely a point of consideration.
There are a million little markers in our lives of who we are and where we come from; our cultural norms, our socioeconomic background and aspirations, the influences upon us from home and society all these things have an effect in general terms on how we dress, style our hair, talk, name our children, socialise etc. Because we are part of a society with norms and values and the average person makes connection between the things s/he sees and remembers them. It's a normal and healthy behaviour. It is how all children learn. Spotting patterns and having expected outcomes. It even keeps you safe. Those alarm bells that ring sometimes or the sense of unease you feel, comes from experience and an innate ability to relate the immediate to the lessons of the past.
And of course we do it with names. Of course we do. If I am told that the other couple attending the same dinner party as me is Ludmilla and Ptolemy, I might reasonably associate those names with a particular group or socioeconomic background. I might reasonably assume that Chantal and Dave come from a different background to Ludmilla and Tolly. What makes me a twat is judging them in advance for this, assuming either couple is better or worse, clinging to preconceived notions if my expectations are wrong.
All spero is doing is pointing out that Jayden is a name which has some of these values attached. It is not a reason not to use it if you like it. It isn't a death sentence. All children transcend their names. But people ask on baby names because they want to know how the name is perceived.
FWIW, I have only ever met one Jayden and one Jaiden. Both belonged to the socioeconomic group sometimes associated with the name. Sample size of two and tells you nothing about their personalities, prospects or parents in real terms.
