I'm looking for some input/opinions. Sorry to pose so many questions and my apologies if I offend. I'm trying to figure some things out.

Do you have a pronoun preference? What do you think of the pronouns zie/zir? (Is there another one I'm missing? Are there other gender-neutral pronouns I'm not aware of?)
Would you be offended by an individual who presented as male or female using gender neutral pronouns for himself/herself/zirself? (Is that right?)
Would you be offended by an individual referring to other people (just in general, not people who identify outside the gender binary) using gender neutral pronouns - i.e. if someone used zie/zir as default pronouns and only used she/he if asked?
Thanks
