Uhh.... if people tell you they're going to be offended if you continue to misgender them, then any continued misgendering by you is - by definition - going to be an instance of you wanting to offend those people and you aiming to give offence.
All current guidelines make it pretty clear that society at large is going with gender-based pronouns. But by all means, launch your own campaign to insist on biological-sex-based pronouns if it's that important to you.
It seems likely that the use of pronouns is evolving, to some degree at least, in English speaking societies. Whether this is occurring in "society at large" IMO remains to be seen. I have never in person encountered a person who makes a point of using non-gendered pronouns. If I was not reading such interesting discussions on these boards I might be completely ignorant of the fact that this is an important issue for some people.
