Have you read my Geoengineering post completely and thoroughly?

I mentioned this:

You would say, If they are spraying that harmful chemicals in our atmosphere then they too would get affected.

No, not really. They have tons of advanced medicine and technology and they command the military to not spray over certain areas or regions where the "bloodline/relative" of their kind live.

They basically live in shielded areas with an availability of healing tech that can heal you and protect you from this poisonous chemtrails pretty easily.

I am aware of those exotic technologies and their workings to some extent.
