You've strung a lot of words together that are not attached to reality. Plenty of people are acting very scientifically with regard to trans people—there are hundreds of studies in this regard. "Correlation is not causation" is the beginning of the conversation about the relationship between the two, not the end. (Observational data plus a solid theory is a very powerful way to establish causation.)

The idea that social acceptance of transness is causing more people to identify as trans is is not entirely without merit, but needs to be thought about critically. It is true that people who have low-key gender dysphoria would treat it with increased salience if they became more aware that trans people exist, but that is very clearly a good thing. Society should generally allow people to be true and happy to their selves.

Moreover, while the general direction of social progress has been encouraging, the magnitude of it has been relatively small. We have a very long way to go before we can even begin to control for social stigma as a factor in trans suicidality rates. This last point is evidenced by comments in this very thread.
