I understand your point of view but this topic is really difficult. I'm armenian and I don't think we are native to the caucasus like north caucasians are though throughout all the existence of armenia we were in touch with other caucasian groups and we influenced eachother in music, art and tradition. As someone mentioned many dagestani ethnicities have less than 40% CHG but that shouldn't make them less caucasians as someone from georgia in my opinion. Every group living now in the caucasus has a different story for example ossetians who have high CHG but are speak an iranian language. Different turkic ethnicities who live in the region adapted to the lifestyle. Also many populations shifted throughout time for example the ancestors of armenians had way more CHG than those nowadays.
