OP, in the nicest possible way, the endless lols and emojis don’t make you come across as ‘harmless’, they make you come across as silly and inarticulate…!
Are you saying you're not in fact like this, and are performing stupidity because of some idea that it will make people like you and find you relatable? Who taught you this? Do you also do this in real life? Do you do it at work?
Surely, as the underwhelmed responses to your post about ‘trying for a girl’, and which of the names you listed was ‘less silly’, you realise this really doesn’t work as a way of signalling likeability?
If you’d written it in plain prose and said ‘We’re hoping to have a girl next time, and are a bilingual family hoping to honour some relatives — what about these names?’, you’d have had completely different responses.
Most posters aren’t ‘bitter’, your posts just didn’t strike them as ‘likeable’, and, not having met you, the lols and emojis made them think you were stupid enough to think you could definitely conceive a girl using internet tips and the Chinese lunar calendar.
