If communities want to go down that road, fine, but then they need to get out of this weird limbo where some views are allowed and some aren't. That means that someone must be just as free to say, "I believe the rust crab should have a normal gender because non-gender-binary is not a thing." without getting banned or cancelled. Right now it's reverted to a very don't-ask-don't-tell-like environment where one can either speak in support of such things or not say anything at all, effectively pretending to agree just as in your military example servicemen had to pretend to be straight.
