That speech does in fact creates reality. Using the masculine form of a word to refer to a group of people does mean, that you actively exclude all the people who are not male. People may not realise and say "dont be so shiny about it", but for trans people it does mean quite a lot how people refer to us.
Also that cis mans literally have to shut the fuck up if people would like, that others could stop using male words as default. Of course you dont feel excluded/discriminates, but I do since I Am definitely not a man and I do not want to be referred as one.
