People are 'triggered' (ugh) because its symptomatic of a culture of slavishly following fashion, and of not being able or willing to reject stupid new ideas.
Same as the furore during the run up to BFV - women were not then, and should not now be (for reasons obvious to those not infected with progressive brain worms), considered for infantry fighting roles.
Similarly, the idea that elite military units might contain 'enbys' is ridiculous. Hence the ridicule.
How fragile is your masculinity that you get bothered by the gender of character in a video game though?
