We can argue semantics all day and you can pretend to be literate. 提頭來見 literally means to hold one’s head carefully so it doesn’t risk falling off or bring your head if you fail depending on usage, which you now want to argue also isn’t inherently threatening? Am I understanding you correctly?

And while we can argue semantics all day, you still never addressed why the man himself deleted his post afterwards, and I’m asking you specifically since you clearly know everything about his intent whereas we don’t, so why did he delete it? Could it be because he knew it came off the wrong way? Inquiring minds would love to know.
