you should still use their pronouns

I am so glad you chimed in on pronouns, because it demonstrates your interest and that you care.
For clarification, it might be kind to find out what you mean,
by defining your personal understanding of pronouns

-personal pronouns
-relative pronouns
-interrogative pronouns
-reciprocal pronouns.
-demonstrative pronouns
or
-indefinite pronouns

Which are you referring when you say should? These technically are not their pronouns, as this is the King's Language we are ALL using. These are his pronouns, technically.

How am I supposed to magically know others pronouns are, in order to use them,
w/o first learning whether they actually know what
pronouns are within the Kings English Language Mate?

could, would, should
tis but one opinion
yours. Own it.

we should normalizes introducing ourselves with our name and pronouns so everyone you meet knows your pronouns and businesses should have their employees name and pronouns on name tags

It's okay.
If you don't know what Pronouns are within the King's English that we are communicating in, especially if you wish to myopically focus upon Personal Pronouns, you can still learn.

Let's don't and say we did.
You can keep your "should's"

Dungeons and Dragons are the child's play of El Diablo, and as such are very HOT.
