"This will especially be the case when new truths emerge from scientific inquiry that challenge age-old cultural thinking (e.g., concerning gender and sexuality) that may have come down to us along with our religious beliefs. That thinking will have to be re-examined in the light of a new understanding of the truth."  
Are you seriously stating that science will someday acknowledge Gender Identity as truth?  We are no longer born either male or female, we can decide that for ourselves at a later date, and that gender identity can change back and forth, even daily.  No more need for DNA, XX or XY chromosomes?    This has nothing to do with religious beliefs, but strictly science. 
You mentioned the March for Science, but I would be interested to know what percentage of the participants actually believe in this new pseudoscience of  Gender Identity.
