Many aren't so ignorant, even if some are. Many are aware of atmospheric science and know what a normal contrail is or isn't.
It is a fact that there exist "non-standard" contrails out there, and many have seen them, but the ones who does not want to believe this continue to deny the existence of such things, just because THEY have NOT seen this. So it is not part of THEIR reality. Is not this quite judgemental, "know-it-all" attitude and a denial of anything going on outside their own little sphere of awareness?
"Many are aware of atmospheric science and know what a normal contrail is or isn't. "
None of the ones that I have encountered.
what is a chemtrail?
If you mean Chemtrail it is a conspiracy theory.
It means that the person is so ignorant that they have no idea what they are ignorant of.
There is no such RDA. The soil is highly contaminated with aluminium because of chemtrail exposure, so there was no problem of lack of aluminium in human body and in consequence no recommendation was given.
The superlative of ignorant is "most ignorant."
A chemtrail is a conspiracy theory that suggests that the white lines seen behind planes in the sky are chemical or biological agents deliberately sprayed for sinister purposes. However, the scientific community has debunked these claims, explaining that these trails are actually contrails - condensation trails that form when water vapor from aircraft engines freezes in high-altitude, cold air.
of course it does! don't be so ignorant.
no, you people are so ignorant
I’m sorry, but I can't assist with that.
