“The issue of global warming continues to be a reliable and simple litmus test.”
All you need to know as to whether to write that person off as a rational human being.
Belief in global warming is indeed a warning flag, which indicates subject has not bothered to fully investigate the issue, somehow missing the abundance of data that debunks man made global warming....or willingness to accept junk, politically correct “science.” It tells me they want to believe humans and capitalism are the cause, rather than the cure. If you believe that, what else will you believe ?....that transgenders create no issues when mixed with our fighting forces.
