Do you work in higher education? I can assure you adding (he/him) was not my decision, I was TOLD to add it to zoom signatures for seminar, lecture business by my highers, if you choose to believe that or not is up to you.
No, I work in law and I don't believe you were under a contractual obligation to state your pronouns as that would be a breach of the Equality Act 2010 on the part of your employer.
You chose to state your pronouns and would have been protected by the law had you declined. If your employer framed this request as a mandatory instruction and failed to explain its context or your right to decline, then they are also potentially breaching their duty to you as an employer.
Obviously, since you were happy to comply anyway, none of this is directly relevant to you. But i do wonder how many of your colleagues feel under pressure to state their pronouns under the false belief that they're contractually obliged to do so.
Furthermore, your employer is potentially harassing your female colleagues by forcing you to remind them that you are a man at every turn, and the practice is also potentially indirect discrimination as women are adversely affected by everyone adding their pronouns to a far greater degree than man are, because the playing field is not equal.
Er, context. my qualifications were in response to a direct accusation "You have no awareness or concern for the effect it has on women who see the issues and are affected by gender ideology."
I simply put my qualifications to show I in fact do have a modicum of awareness. I have no 'argument' or 'agenda', as you see it.
If you need to state your qualifications to prove that you have more awareness about how offensive your comments are to women than your comments actually suggest, can you see how it's likely that you weren't displaying your knowledge of such awareness effectively on this thread?
I didn't accuse you of having any sort of agenda - my take on it was that this is your academic area and so OP's question interests you, you have direct experience of the issue of being a male who states his pronouns (which I'm grateful that you shared), and you inadvertently made some comments that came across as insensitive and which appeared to be dismissing the experience of women. I took this to be because of your own blind spot as a result of your being male and never having been in the specific situation of experiencing misogyny directly.
