I don’t think that whatever happened today has anything to do with how she or he or they may have wanted to identify,” he said. “And I wish people would kind of leave their own personal biases out of this
It's so frustrating that so many of the people objecting to people asking if the shooter was trans think it's about people being anti-trans, or caring whether the shooter was trans specifically, when in most cases, it's about trying to translate the media reporting into the actual facts of the case.
If the shooter is reported as female and trans, then anyone who doesn't subscribe to gender identity ideology can understand the case as "reported female + trans = biologically male", but if they aren't trans, they can interpret female = female as gender identity actually isn't relevant in this instance, but there's no way to know which without finding out the trans part of the equation.
It's merely a consequence of the way gender identity is typically reported as if it were the person's sex that people understandably want to check what female actually means to the person reporting the news, especially when violent crimes perpetrated by females are so rare.
If the fact the perpetrator was "female" is of sufficient relevance to report, then it's reasonable for the public to request clarification as to the specific meaning of the word female in this context.
We live in a world where female might mean female or it might mean male, which is what prompts so many people to ask for clarification and bring up transgenderism - not because people are anti-trans but because just stating "female" isn't sufficiently clear any more.
