I default to whatever the traditional apparent gender would be assumed I.E. you look like traditional woman/man I refer to you as such. Then I allow myself to be corrected if it’s inaccurate.
The intent isn’t offensive and I’m not going to ask each individual what pronouns are preferred but will respect whatever I’m informed is correct in each instance. I think it’s being made into a mountain when it’s really just a mole hill. You can’t expect every human to automatically be correct or informed or even default to a neutral when it is not yet the norm.
It seems too trivial to be butthurt over if it isn’t malicious, especially upon first interaction. Let the person know, then if ignored or dismissed it can be considered offensive.
I don’t get upset when people call my Bugles potato chips, they are little crunchy cones of heaven
