As a professional scientist, I recall learning that it is the very best part of the scientific method that hypotheses are developed by unbiased and careful observation, then rigorously tested; and, further testing is always welcome (and invited).
Polical correctness for what arguably does not qualify as an hypothesis is the precise opposite of the scientific method.
I'm embarrased that so many of my fellow "scientists" (and others who should know better) are unwilling to be professional regarding this critical topic

embarrased = embarrassed (embarrassing mistake)
