Only if you're being wilfully obtuse. There's a vast difference between stating your own preferred terms of address and attempting to foist them on other people.
Ie. if Philip suddenly introduces himself as Phyllis one day, I'll call him Phyllis. If Phyllis states personal pronouns habitutally, fine. I won't be acting upon the expectation to do the same.
Gender is a distinct category from sex and its assumed relation to sex is entirely arbitrary. It's a set of social stereotypes based around the expected behaviour and appearance of the sexes in accordance with social convention. At best, it's a diktat on people's behaviour, usually disseminated by the most dominant social groups. At worst - and this is where the rot set in with pinkification etc. - it is merely someone's marketing strategy.
The idea that 'gender' is a corporate concept is an interesting one indeed: I'd love to read any studies carried out into how far it's dependent upon capitalism or vice-versa. The trouble is, such a study would never in a million years net any funding.
What is plain, when you drill down into it, is that gender has little, if anything, to do with sex. But it undeniably exists, (albeit nebulously and no one seems able to define precisely what it is). IMO it's an extremely damaging concept to men, women and trans people alike. Toxic masculinity has been extremely harmful, but as the less dominant sex, women in particular have suffered as a result of this.
Why on earth would I want to 'identify' with the instrument of my own oppression?
