Nope, because now you’ve started to provide more information than is necessary to identify yourself.
My interpretations of the Florida law for your examples, but of course I’m not a lawyer, this isn’t legal advice, and my interpretation of the law is different than what I believe is ethical:
I introduced myself as Mx Endocrinous,
This is fine. You’re just giving students knowledge to identify yourself.
wore nonbinary and trans and gay flag pins,
I think this is probably on the borderline, but I don’t believe the law would allow this. You’re conveying information beyond what the students need to know to identify you.
On the other hand, I think the law also prevents someone from wearing anti-trans and anti-gay flag pins (if those exist? I’m not up-to-date on hate symbols).
had an it/its pronoun pin,
Legal IMO. At it’s core, it’s just two English words on a pin which have meaning far outside the sphere of gender identity. If you’re using it to indicate how students should refer to you, it’s also legal IMO.
and referred to myself as dronegender,
Not legal IMO. It’s outside of the basic information necessary to have a conversation with or about you.
I don’t personally this is a particularly good law, but I also don’t believe it is as restrictive as you’ve described it. And I’m not a lawyer. The law is written about “classroom instruction,” so as long as what you’re doing doesn’t constitute that, you’re fine. The difficulty, as you’ve pointed out, is defining what that means.
Depends, some loads are subsonic especially for suppressor use. I’m looking at you, 300BLK
