We can acknowledge and accept trans people without bulldozing millennia of human culture. This has nothing to do with "speech", free or otherwise.
> We are now at a stage where a twitter mob would see "men should not be allowed to compete in women's sports" as a bigoted statement.
This is clearly referring to the present day public debate of whether trans-people should be allowed to participate in men/women sporting.
If you think I'm wrong, could you point me to the ongoing non-trans-related debate regarding men vs women sports?
Why are you beating this fake dead horse? Free speech is protected, offensive or not. There are no governmental consequences.
However, it also covers and allows for the replies, tweet storms, public shaming that occur when your free speech is racist, sexist, or bigoted and malicious.
That's what this debate is /actually/ about - you just want protection against backlash.
