"Fear coded" is an interesting construction. That is easier to say than "betrays a fear based thought process", which is what it sounds like to me. Different enough from something like 'fearful thinking' that I can see why it would be used.
The Pleiadian stuff is just too much nonsense for me to want to understand anything used in that context.
I searched just 'pleiadian' on google and got both an 'About' and the 3rd result linking to a misspelled PDF on IRS.gov about "ancier& extraterrestrials" Um what? I've never been so tempted to click a link that I know I shouldn't click.
